We have wordpress site also vbulletin and pligg and buddypress is running in website. Till now all the users need to login to all the different scripts to access but we want to have SSO single sign on for all the scripts and login link should be at the top right corner, once the user is logged in, he/she will not need to login to diffrent scripts.
Once login will be automatically logged in to all scripts.
So what we want is to have a bridge between vbulletin, wordprees, pligg and buddypress in order to share same logiin and registration database. We need SSO for all the scripts and very minor css tweak in header styling, very minor.
Please only bid if you are really interested and willing to work asap and complete it as early its possible.
