Wow frenchie, did you make both of those? How long do you spend making images for these games?
As for your avatars, I'm not really sure what the problem is. Everybodies avatar looks about 50x50 to me as well (though I'm not measuring them or anything). I had to shrink down the pic you made of the space squid though, it was originally a 200x200 according to my machine, and the site won't take bigger than 144.
Edit @ Lumo, OMG. A warning that the rules have been updated? Fleee!! Flee in terror for the end is nigh!
