1) The Abilityfest
was for powers which already exist. It simply required members to draw the powers, or at least their interpretations of them.
2) The Art Contest '06
was for non-Kirby characters with Kirby-like copy abilities.
3) Blokes are always creating "make ur own ability" topics in these forums, although they probably contain a lot more typos than that.
So, it doesn't seem that a Make-Your-Own-Ability contest has ever been run through the actual site. Or if it was, none of the files exist anymore, which I would find hard to believe since KRR never deletes anything... ever
.... and usually has it in triplicate.
Oh yeah, and
4) The Make-A-Friend is done by Bimblesnaff. You would have a lot more success going to him directly, what with him pretty much dominating the market on new content at KRR (Gurus, Polls, Make-A-Friend, Election, etc.
). Really, what other staffer would you expect to make such a feature?
