I don't think the tags come through to me unless they're associated with a fandom. What I'm going to do is create "Glorantha - Tabletop RPG" as a fandom in the tag set as that variation of it doesn't exist in the archive at all, let alone as a synned tag, and once it exists you should hopefully be able to add your noms to that. Let me know if that works; if it doesn't, please can you provide me with the link to your noms page?

ETA: Ah, now that I've cleared the "Already Approved" screen down a bit I can see your noms, they have come through as though they were King of Dragon Pass ones. I'll reject them from that fandom and add them manually as Glorantha ones.

ETA2: Looks like that's all worked; you should be able to find "Glorantha - Tabletop RPG" with your noms in the "Uncategorized Fandoms" section.
