Okay, here's my idea: "Where's N.o.L.o.N". (get it?)

Create an avitar named NoLoN, and hide him in the posts, say 10?, 100?, and we have to find him/it, kind of like the Easter egg hunt, but this avitar would be unique to this site, maybe a compilation, characature-ized, of course, of the staff. The winner is the one who finds all, with occassional special bonus N.o.L.o.N.s, then weekly, or whatever, you pay the winner, plus with maybe consolation prizes of hints for the next puzzle.

So, waddya think?

NLNLoni, Thanks for the suggestion! Sounds fun
