I am currently running a forum with Invision Power software and will be adding Wordpress multisite with buddypress to it. I have multisite and buddypress installed and working. I am using a single sign on between my IP Board forum and Wordpress found here: http://community.invisionpower.com/files/file/6089-mt34-wordpress-ipsconnect/ All existing members are added into the WP database once they navigate to a WP page.
- Auto create a WP blog/site after successful registration (added to WP database) based on their username
- Domain of blog/site to be domain.com/user
- Be written as a plugin
