Changing forum avatar is too hard and lengthy a process.
There is not enough information.
For example, where it tells me to upload an image, it says to upload it to my "profile" page. It would be nice to have a link to the profile page! I only found it by accident. I thought it meant my web profile, so I poked around there for a while first.
It would also be useful to know how big an image I can upload. Trial and error is okay, I guess, since this is clearly going to take several days.
And while I'm whining... the fact that I have to wait for someone to APPROVE my image, really makes me not want to do it at all.
