How about a contest for the fans to create the next clan? This how it could possibly go...
1st round: People send in a paragraph describing their clan idea. Like a pitch.
2nd: The top 10 are selected and asked to go into some further description like what they're about (their alignment, concept, KO animation, etc). These are voted on by the fans.
3rd: The top three will be given a promo with an example of what three characters would be like. The winner will be the next new clan.
Just make a promotional thing out of it to attract older fans and new people. What do you guys think?
