So they choose the username? like if my username on my forum was "bob" and I went to sign up for this, I could take say, "bobrules" or something? This isn't what I wanted, I wanted it so they do not have the choice of that, I want it so it takes their username [unless it has illegal characters...etc...it should give an error message...], and sticks it like this:
My username: Tha Rock
I sign up for NeoMail and my email address automatically becomes:
Tha_Rock@sdsym.net [my domain]...
