Perhaps a Macro contest would be fun.?
Reading the cat macro thread is awsome. Funniest stuff I've seen in a long time. maybe once a week LFG (or a member) can post a random picture and for the next week members add text to it. Evereyone votes on which was the best of the bunch.
Example:
This pick is posted
Then someone adds text
dunno just an idea, and could make for some funny threads to read at work.
