I accidentally typed a ".com" instead of a ".net" at the end of my email address when registering my nick on irc. After i realized that I wouldn't get the email because of the screw-up, i tried again with the correct address, but it won't let me do it again. Is there a period of time I need to wait? Or something that I have to type in?

For many networks, it is 48 hours.

Find an ircop get them to delete your previous attempt or wait the 24 or 48 hours as stated
