Hello Jeremy,
We’ve been using this plugin for a few years now on our sites, I can vouch for the support and documentation.
We’re very happy with the plugin.
On a side note, don’t pay any attention to the condescending little parasite who commented immediately after you. He’s on some sort of twisted quest for authority and often renders this forum with his unsolicited views and conjecture. Definitely not representative of the s2member support that I’m familiar with.
This is a very comprehensive plugin and there’s a lot to learn.
Hang in there, you’ll be glad you did.
