Your not allowed to give out your e-mail address in public because of spammers. I think the same goes for instant messenger names. If you want to give another user your e-mail address or instant messenger name then send them a PM (personal message).
Weazel200 said it all (sigh). Read [bold]Rule #10[/bold] under General Rules http://forums.afterdawn.com/thread_view.cfm/2487 . I guess we can close this one.
You don't want SPAM. If you want to give someone your email or messanger screenname, send it to them in an private message (the little face with an arrow.)
