Are there any specific size limitations or file types for avatars for this site?  I've searched, but I can't find anything.  I'm trying to upload an avatar, but so far I've been unsuccessful.

what error message are you getting?

Can you post the avatar in this thread and i can try getting it in there for you

I don't get an error message.  After I submit, the page looks like it's trying to upload but then goes blank.  I see "done" in the bottom left, but the rest of the page is blank.  I can't post it here because it's just on my hard drive.

Ah...thanks.  I've never paid attention to that before.  I see the pic I'm trying to upload is probably too big.  It's over a mb.  I'm going to reduce it and try the upload again.

Thanks, Leaf.  I've successfully uploaded it after reducing the size.
