I think it’s time for a new thread, the game has changed quite a bit (Transition to Steam and now USF4). Most probably this will be the final major upgrade to the game so a new thread can be made at this point. The wikis should remain as it is though you can change it’s name to “USF4 Modding Wiki (2014 Update)” from “SSF4 - Arcade Edition Modding Wiki”.
Additionally if there is an option, you can make a sticky link to this thread on the new thread so users can see all the info here whenever they want.
NOTE: This is just my opinion, please listen to more feedback before you make the decision.
EDIT: Just saw the fresh look of wiki, nice work there hunter.
