Since I am a recent member, I am maybe proposing something that you have already done, but here it is anyway.
How about organizing a little avatar contest, where people could propose their favorite member avatars in each of several categories:
- the best of the best
- the funniest
- the cutest
- the most original
ETC.?
For each category, the member whose avatar would be proposed the most often would win.
Just a fun idea like that.
