Dear wordpress users!
I have a WordPress site and I want it to organize authorization and registration of a social network. Of course, for the CMS a lot of plugins implementing this feature, but I need functionality similar to the one that is implemented on mashable.com and forbes.com (facebook twitter login). Clarify the situation. The main thing I need is not only the registration and authorization through the accounts of social networks, but also change the standard user's page on a completely different and unrecognizable (default page wordpress - http://127.0.0.1/wp-admin/profile.php and the mashable http://mashable.com/follow/home/edit or forbes - http://blogs.forbes.com/account/ ). Without the traditional interface, which is similar to the admin interface, to a strict separation user / administrator. That is the page that will not look like on the inside page of the administrative interface. Surely you understand me, if ever commented on mashable and use wordpress.
I have confidence that such a plugin for wordepress already implemented, given the popularity of the platform. If I'm wrong, could you tell me how to do it yourself. Maybe - already there are manuals on the Internet, and if so I would appreciate links.
*note - Mashable and Forbes.com use WordPress
Sorry for bad English.
