Some ideas and key components of a well developed membership website should include (please add to the list), but are not limited to:

• Newsletter Sign Up

• Different Level Member Registration Forms with Payment Processing

• Member Center or Account Management for Users

• Member Networking (Forum, Blog, Messaging, File Upload, Video Sharing, Groups - something a la Drupal Commons - but with Single Sign On)

• Membership Directory for Public Search (we are actually working on an integrated Google Map View to show front end users the location of the member within their profile - if anyone has done some work in this area or has some good examples, please post)

Back-end:

- Member Management (payment processing, automatic invoicing, automatic renewal reminders, member reports, automatic member upgrade to different member level, etc)
