I know Laura mentioned about a month ago
Facebook Connect is something that Ning is looking into.
I wanted to throw my two cents into this, since I feel there'd be a lot of benefit to having Facebook Connect functionality available in our networks. For instance, we run a 3000+ member fan page on Facebook and being able to integrate their experience through FB Connect would go a long way towards helping build bridges between the two spaces.
Also, I saw a short video from the guys at NingMods showing how FB Connect could be implemented as part of a network on Ning:
Is this something they were able to do b/c of a particular way in which NingMods is set up that is unique to it?
