database wp_capabilities for membership

I recently installed this plugin and MarketPress, great job on them by the way, however when I was testing the login process, I was still logged in as an administrator. Membership made me into a member and I had to reset my wp_capabilities to a:1:{s:13:”administrator”;b:1;} in order to be admin still, however, I noticed there was some sort of wpmembershipadmin or something like that before. What exactly is that setting?
