You cannot remove your url. That is something only SMF For Free can do.
But there might be a way around this.
If there were invalid characters in your username, it wouldn't have let you register. What you can do is use the "Forgot Password?" feature and recieve an email.
In that email will be a link to change your password as well as your USERNAME. Check to make sure this username is correct.
yeah I tried this before I sent this bug report. It didn't work because my username was accepted with the unnecessary characters and it says that my email is not recognized. therefore it wont send the email. so when I try to make a new account, it wont let me use my same email(
zstaylon@yahoo.com). So this is really weird and I hope that the owners of smfforfree can delete the url off their hosting pages (or something they use to control the websites url's.) so that I may be able to do it all over again.
thank you for the help
