This worked perfect.
I copied and pasted the code into a new PHP doc, that I created in Dreamweaver. Then I put in the directory above, and I named it “s2-hacks.php” as recommended by Krumch. It didn’t work, because I didn’t have the proper starting and closing PHP tags, so I added those, then it worked. However, it would send out two emails, one saying you are a subscriber, and the next saying you are a s2_member 1.
So, I don’t think there is a solution. I don’t want this to go out when they become a subscriber, or a s2_member 1. I only want them to get an email if they become an s2_Member 2. I hope this helps, and thanks for all the help to everyone. I hope this explanation can clear up someone else question. Thanks!
