For expansions, incase you don't know how it works,
They use a thing called a checklist.
This is the Official SSF2 checklist. Straight from the dev section.

Also, the rules of expansions...
1. At least one animation is needed before an expansion may be started
2. You need to make sure that an expansion you are claiming hasn't been started or claimed
3. NO recolors
4. No large sprites. This includes SF. There is no fine line, so they will me judged my one of the staff.
5. Nothing rude, or offensive. Keep it something that could be shown on Daytime TV. ie: no nude character expansions
6. No stickman expansions
7. Make sure to use the checklist when starting an expansion.
8. The expansion checklist is subject to change
And, if expansions are made, I believe the forums subsection needs a new rank.
The E.A.T:
Expansion Acception Team
These are the dudes who judge your overall expansion for it's quality, and effort.
INB4 "Lets make em now." , think about it.
I would just wait for expansions until the entire roster is confirmed, and is not changing.
I don't reccomend revealing the roster yet though...
