Yeah I remember when I first registered I could not get it to hold my custom avatar.
It worked now though
I might even make it a little bigger. Right now it is 60X60 and according to the upload area it could be a max of 80X80.
Question though? If it is an odd size like 80X76 etc. will it be distorted to 80X80 by the forum?
I did have one forum distort it to be a fixed width/height so I had to put it in a transparent square.
