OK instead or replying to the seemingly undending daily torrent of "where's my thread gone?" threads - I know it must become quite irritating - why not ignore them and focus on my feedback, which I think is quite valid. Don't you want the sign up page to work properly? I know I am eager to change usernames ( I assume it is still alright for me to submit my current one for a new one so long as I tell you guys), but asides from that I think it is probably something the admin would want to know about. I think it is a mistake and probably should be corrected, it kinda doesn't sound like a difficult problem to fix either, but I might be wrong there. Normally on sites there are restrictions on passwords, and usually usernames, but I have never heard of a forum restricting the username to between 6 and 10 characters, I can't think of a logical reason for having that.
