"You must spread some reputation around before giving it to Grich again."
Heh. That's funny... I was just planning on starting a "Sane's Weekly Challenge" thread sort-of-thing, where I'd propose three algorithm challenges of varying difficulties (simple/advanced/challenger), that shouldn't take any more than 10-30 minutes to accomplish, each week.
I like the notion, but I'm not sure if it's suitable to have an entire forum for challenges. I'd say extend the Algorithms and Design forum to include this idea. That would also help with expanding what is one of the smallest forums on PFO.
