There is a contest going on here:

Have fun!
A very nice contest indeed but it seems some of us might not be able to participate. The requirement that one outs on both the avatar and signature is a tall order to some. We are already enrolled to other signature campaigns and thus are wearing their signatures. I cannot remove the signature to play the pd contest only to lose later. Signature campaigns are currently very competitive and removing your signature will make you lose your position to some one else who is already waiting to join.
It could be better if people chose between the avatar and signature or both, if you can.
