Social community login : User information

Hi everyone, My website is using Gigya's social plugin to allow users to login via their favorite network (Facebook, Twitter, G+, LinkedIn, etc.). I managed to add the plugin and set all oAuth process correctly. However, I now need to use provided information via the oAuth process and I'm blocked here. You can see the login page here : [login to view URL] Note that you won't be able to go to [login to view URL] as we have recently migrated from [login to view URL] to www.thebbcmusic.com. We are using this situation to improve and make some test on www.thebbcmusic.com. You can still navigate on [login to view URL] on pages, for example [login to view URL] So basically, here is what I want : 1- Have events managed and information provided used to : a) Detect if the user have not yet registered, in which case it redirects him to the register page and use provided information via oAuth to fill register fields easily b) If the user is already registered, log the user in and redirect him to home page I'm using Wordpress v3.2.1 Buddypress v1.5.1 Information about Gigya's UI to grab users information can be found here : [login to view URL] Sincerely, BBC
