This is my first "real" MOD so be easy on me!
This MOD allows registered members to e-mail people, inviting them to join in on the forum.
I ripped most of the code off of pop_send_to_friend.asp and worked with the code to get a link added to inc_header.asp. The link to invite will always be accessible from every page because it is in inc_header.asp
As far as a rating for ease of install I would give this a 2 (1-10, 10 being very hard).
Thanks to hayleypink for the suggestion!

P.S. If for some odd reason the link to download does not work then please use this link.
