I am now having the same problem. I want to change my avatar but when I go to upload it from my computer, I get a blank screen and this as the web address: http://www.wnff.net/index.php?action=profile2.
I was able to change mine yesterday without any problem.
When I entered that URL, I received a user profile did not exist message. I hope WNFF hasn't declared you dead like Dallas TX did to me in September.
