Looking for a way to store email addresses. I've coded a forum which is
nearing completion.. one of the things I'd like it to be able to do is
allow users to "subscribe" to something and if a new post is made that
they'd be interested in it would notify them. The only way I see of
doing it is for a group or topic to have it's own simple single array to
hold email addresses.
