This is a too late answer but it may help someone...

To login and register on mojo portal using fb, the easiest way is linking an OpenId, to obtain openId you must create an account in JanRain and setup a fb application for grant access the seccuence is this mojoPortal-JainRain api- fb then the procees is forwback.

This is a complete tutorial Using socialmedia to login MojoPortal.

the only disadvantage is that the free account on JainRain limits the number of registers for month to 2000 I think. I hope this helps and sorry for my bad english XD
