I use this software for the School of Podcasting. It ain't pretty, but it works.

aMember is a flexible membership and subscription management PHP script. It has support for PayPal, BeanStream, 2Checkout, NoChex, VeriSign PayFlow, Authorize.Net, PaySystems, Probilling, Multicards, E-Gold and Clickbank payment systems (see list of integrated payment systems) and allows you to setup paid-membership areas on your site. It can also be used without any payment system - you can manage users manually.

aMember Pro also supports integration plugins to link users database with third-party scripts, for example vBulletin, Joomla, WordPress (see list of integration plugins).
