The exchange will happen at the Archive of Our Own. If you don't have an account, sign up for one soon in order to participate.
From the Rules and Guidelines post:
You can nominate up to 5 safety fandoms and up to 10 longer fandoms.
Nominations will be open for two weeks. Please only nominate fandoms if you are interested in participating in the exchange.
There are two tag sets for the spring exchange: one for safety fandoms (240 minutes / 4 hrs or less) and one for longer fandoms (241 minutes or more). The tag sets are separated to make it easy to see which fandoms are classed as safeties and which are not.
Safety fandoms will have to be nominated specifically to the safety tag set, and longer fandoms to the main tag set.
After nominations close, the tag set moderator (with assistance from other exchange moderators as needed) will look over all nominated sources. They'll be checking for two things:
- Does the fandom fit the theme?
Nominated fandoms are expected to fit the guidelines given here. Anything needing clarification will be posted to the exchange Dreamwidth to give nominators a chance to explain their nominated source's relation to the theme. If a fandom tag overtly does not fit the guidelines, moderators aren't required to ask for clarification; anything can be rejected from the final tag set if it doesn't fit, and the final decision on all approval/rejection of fandom tags is with the exchange moderators.
- Was the fandom nominated to the correct tag set?
The tag mod will also be checking the total runtimes of nominated sources to make sure that all safeties (and only safeties) are in the safety fandom tag set. Any duplication between tag sets will be removed at this point.
