If you wanna do it, then do it There's no particular rules surrounding these challenges (:
Musta read that wrong. 
Edit: And looking at the older challenges' starters, double oops.
What I meant was: only mods can start the challenges, and there are guidelines as to what to make in them, but if you want to bypass some of the rules, you're still welcome to post the result in the appropriate challenge thread. As long as it doesn't stray too far.
'There's no particular rules' was of course just me being more or less wrong, heh.
