If you haven't realized, you can set your avatar. If you reach x amount of posts, you will be able to upload your own custom avatar (no bigger than 75x75). Now that we have more room, those of you that like to make avatars can send them in again at a larger size. Larger size means more detail!
Also, If I see unneeded posts being made just to run up the post count, they will be deleted and your post count will just go down.
