The collection is now revealed. Go forth, enjoy your (and others') gifts, and comment!

There are a handful of works that won't show up when browsing the collection via the fandom view, as their fandoms do not yet have canonical tags. Here are direct links:

• NASA "Visions of the Future" Travel Posters
  • My Home in the Cosmos
  • A Century of Savvy Travelers: A Look Back at the GSST Project, 100 Years On
• Iconoclast - Symphony X
  • Shadows on the Wall

Treats can still be uploaded for another week, until creator reveals.

Finally, thanks again to everyone for making this such an easy exchange to mod.

ETA: Don't forget to redate your work, especially if it's in a high-traffic fandom.

The final pinch hit is now in the collection; huge thanks to everyone, but especially our last minute pinch hitter. Assuming nothing happens to my ability to access the Internet come reveals time, the collection will be opening on time. (I don't intend to open early, as I am conscious that people may well intend to revise their works considerably over the next sixty-something hours.)

Treats (which do not have to adhere to any minimum requirements) can be added to the collection any time up until creator reveals on the 15th.

If you're a frustrated gift shaker/just generally interested, there are two unwrangled fandoms in the collection that I've become aware of when checking over the works:

• NASA "Visions of the Future" travel posters (2 works)
  
• Iconoclast - Symphony X (1 work)
  

I will be linking to these from the DW comm directly come reveals, to try to compensate for them not showing up on the AO3 fandoms view. If there are other things that should be on this list that I've missed, do PM/drop me an email to let me know.

Remarkably, at this stage there seem to be no post-deadline pinch hits. (According to my records, everyone who hasn't submitted yet has asked for a short extension, so please don't worry if you don't have a gift yet.) Thank you everyone for being so organised.

Still looking for a pinch hitter for Pinch Hit #7.

As of the time stamp of this post, there are 24 hours left to post your works. Thanks to everyone who has already uploaded, and to those who have already been in touch about extensions.

My ability to get online over the next 24 hours is turning out to be somewhat more limited than I would have hoped. My main windows of opportunity for doing exchange admin look likely to be roughly between 1900 UTC and 2300 UTC, and then from about 0530 UTC onwards. I will probably glance at my emails occasionally outside those times, but won't be able to deal with anything complicated. So please don't worry if you don't receive an instant response if you do contact me at other times; I will get to your message sooner rather than later.

Works are due in just under a week from the time of this post.

If you think you might need an extension, please email me at worldbuildingmod@gmx.com - I would very strongly prefer to be pleasantly surprised when people turn out not to need them, rather than the other way around.

Existing pinch hits (many thanks to those who picked them up) have the same due date as other works. Any new pinch hits which arise between now and 1st April will have a later due date of 06:59 UTC on Weds 5th April.

I am aware of the ongoing issue with posting works to AO3 being difficult. If you do encounter significant problems with uploading your completed work, please get in touch.

If anyone's interested, of the 18 works already in the collection, 13 are completed assignments and five are treats.

To claim, comment on this post with your AO3 username; all comments are screened. If you get it as an assignment, you got the pinch hit; if not but you see it's been claimed, then someone else got it instead, sorry. (But do consider treating!)

At this stage, the due date for the pinch hit will be the same as other works: Sat 1st Apr 06:59 UTC. (This has always been intended as the equivalent of midnight Pacific time on Fri 31st March, but let me know if I've messed up accounting for DST.)

( Pinch Hit #4 - Fandoms: His Dark Materials, Lock In, Guild Wars 2, Zootopia, Secret World of Alex Mack - Claimed! )

Here is a Google Doc containing all the requests in the exchange, for your crtl-F-ing pleasure.

It is 126 pages long. Wow.

Happy Worldbuilding!

Assignments are on their way to your email, or you can check your AO3 assignments page.

(Thank you to the unmatchable participant for responding so promptly and being willing to extend their offers in several different directions.)

There are three initial pinch hits; details will be posted shortly.

ETA: Since everything ran so smoothly, assignments are out significantly earlier than expected; please be patient if you are currently looking at a locked/placeholder letter! (I would suggest waiting at least until the target time for assignments to definitely be out by, which was Friday night/Saturday morning depending on time zone, before worrying that it's not going to be updated.)

If you are still in the process of signing up, please reply to this post or ping me an email at worldbuildingmod@gmx.com with your AO3 username so I can keep an eye out for your sign up appearing. I can't hold the door open indefinitely but I will do my best to provide a little bit of wiggle room.

If you are still signing up, and you're aiming to provide detailed prompts*, then for what it's worth I would quite strongly suggest that to be sure of making it in time, you go down the route of linking to a placeholder letter and cut and pasting brief details of your strong DNWs into the Optional Details boxes, and then update the letter later.

*please note that prompts are not compulsory - Optional Details Are Optional applies in all directions, and in this exchange in particular many of the worldbuilding tags are essentially prompts by themselves

Letters giving details of your requests/prompts/etc. are not required (requests will be visible throughout sign ups), but if you do write one, you can leave a link here so that other people can find it easily. Treats are very much encouraged in this exchange, and letters are often a good way for potential treaters to find potential treatees.

If you want to advertise your letter, leave a comment on this post with at least:

• Your AO3 username
  
• A link to your letter
  

And (optionally but helpfully):

• Which fandoms you are requesting
  
• Which types of fanwork you are open to receiving
  

If you wish, you can cut and paste the template below into your comment:
<b>AO3 username:</b> <b>Letter link:</b> <b>Fandoms:</b> <b>Fic/Art/Meta?</b>
NB Please don't link to placeholder or locked letters here; if I spot any I will screen the comment in question until you message me to say that it's finished.
