That's odd. I tested it and it worked for me. When editing a custom avatar, under Option 1, make sure to copy and paste that link where it says to insert a url. That's what I did and it worked fine. Sorry for the trouble.
Ah, sorry! How about this, you put up something like a zigzagoon or something of little value in the gts for a swirlix, and i'll trade it to you that way And let me know what your IGN is!
