Not sure... this plug-in doesn't alter how vBulletin does facebook registrations, only what it uses for the default username. So your question would be better for the support forum on vb.com

If a user doesn't have a Facebook username and they end up registering using their real name, will it still put a number on the end if there is a clash?

Any idea?

No, if they have no Facebook username, it will just revert to vBulletin's normal behavior.

Instead of importing their username from facebook can we setup a varible to have them input a name, lets say for my site is a gaming clan, and i would like it to import the name they type in for thier playstation Gamertag. is this possible?

can it import their fb profile photo with facebook connect?

I have an issue. I can't get this to work. I imported it correctly, but no matter what when the person hits connect it instantly registers them instead of redirecting them to the registration page..

Disable the "Enable Auto-Register" setting in your AdminCP settings.

Do we need Facebook connect license for this mod

What is a Facebook Connect license? Do you have a URL?
