Het Swap Exchange

 I just opened up signups, they close on January 26th.

You can request and offer 3 to 6 fandoms, 1 to 10 relationships per fandom.

Signup form is here and the tagset is here.

A few fandoms that haven't been wrangled and will be listed under Uncategorized Fandoms until they are. Also, if you're having trouble finding your pairing, check under Crossover Fandom (applies to a few DC, Marvel, and Doctor Who ships where one half of the pairing was primarily in one series and the other was primarily in another but met in canon crossovers/multiverse situations).

There is also a known glitch where certain fandoms/relationships won't auto complete on the signup page, even if they're in the tagset. If that happens, just copy directly from the tagset.
