I have tried membership, s2member, wp-member, to name a few. My needs were much simpler than these plugins provided. They also caused memory issues using a lot of resources to accomplish all their complexities... Still none made it easy to have individual memberships and customizable forms. Then I found Users Ultra... Finally a lightweight plugin with a very simple set-up procedure. It was so easy I thought I was going to be disappointed with the features... that is what blew me away... I can manage three recurring memberships, free volunteers, and offer all my members a custom profile area where they can blog, post photos, email and more... I can also block access to my wordpress menu which keeps the back-end really clean. Thank you Users Ultra for a great plugin that is easy to set-up and easy to use.
