And if you don't know if it's an email address, then that would match things like an $address() (nick!ident@host.com), which you wouldn't want. Invision Support #Invision on irc.irchighway.net

I don't need it to be amazing or even foolproof. I just want a simple check on a string to see if it follows the basic format of an email address. Newbie
