Getting OpenID to work on an existing MyBB Install

I am the administrator for a forum,The Vortex. It operates o开发者_如何学编程n the latest version of MyBB ver1.6.3. I would like to know how I can get OpenID to become the login for the forums, and also add the users to the MyBB Sql file and overwrite any users that are already registered. This must work on an existing install as I will not be dumping my SQL database to do a fresh install just to get OpenId to work. Any Thought?
