I have put YM to work on several sites of non-profit associations, and have come to immensely appreciate the profound thinking that has been invested in that plugin. It's not "just" a membership management plugin, it's a membership community management plugin, and I have always felt that it is not just hugely underrated but (sadly) not widely enough appreciated for its thorough approach in serving organizations that have paying participants with varying roles for varying terms. Other value adding things were built in like adaptability to PCI compliance, integration with third-party mailers as well as self-hosted mailing support, individually programmed mailing schedule (a.k.a. "drip mailing") support, timed progressive access to content (i.e. more traditional content dripping), seamless integration of Simple:Press forum plugin, support for protected access of streamed media content, support for protection from link and password sharing, and I could go on and on. Glenn, Sean, Barry and of course especially Tim: I'm really sorry to see it go like this. Here's to hoping against the grain that someone, somewhere is seized by a spark of imagination and puts the necessary fuel into a fantastic concept. Not to dis other great membership plugins (and I agree, s2Pro is the most immediately suitable replacement) but I think the WP community is going to miss out on a great plugin that should have fared a lot better than it did. In fact, the GPL sunset clause is a nice symbolic proof of Your Member's well-thought out design.

Much better luck ahead, Mr Nash. You deserve it.
