New changes

This is a deceptively long post, but don't worry, it's mostly details and organizational changes!

The tl;dr important points are:

Offers are 1 fandom minimum
Requests are the same official minimum as last year (3 fandoms with distinct lore to guarantee a gift) but you can initially sign up with one fandom. After the due date if you're out for PH we'll send you a friendly email giving the option to add fandoms to guarantee your gift.
The relationship nomination method has changed slightly. You can still nominate relationships on AO3 if you follow the guidelines (which are the same as last year with some additional worldbuilding options), but we'll be directing people towards a google form as the main nomination method. You can also transfer in fandoms from last year.
Medium nominations will be on a dw post to facilitate discussion of new mediums, with almost all of last year's mediums preloaded into the tagset.
Mediums have been sorted to be clearer and have shiny new rulesets. Almost all of them are exactly the same rules as they had last year, just better organized. Any changes are listed.
Assignment swaps will be the first week after assignments go out
Fills for PHer requests count for minimum
You're able to swap part of your assignment (up to 2k) for donating a template with instructions to the collection for use during the exchange.
Defaulters will go out for PH up until the due date (unless otherwise requested by the defaulter)

We've already started on the tagset and Fandom Transfer is open now ahead of official nominations opening.

If you'd like to see a sorted list of the mediums, check these tables:

Separated by ruleset in this spreadsheet (note that this is sheet where the mod is organizing things, so from time to time during nominations this may have some odd looking columns unhidden)
Ordered by tag in this spreadsheet (ditto above)
