not enough email addresses

see me and a few friends dicided to make another forum, but they dont have email yet and i only have one and i used it on a forum that i dont plan on getting rid of...what do i do?

If i understand your query correctly, you are short of email addresses. So Create new email addresses.

well i cant because i use a school computer and i cant use email with it...except windstream but it costs money to get a new email with windstream.

Gmail or hotmail, create on them. Other than that there is no other way sorry.
