But it needs some customization, because ubb doesn't have APIs. (It seems v8 will have api , but maybe that's php-based , pity. Appeal again , we need HTTP-based APIs/Hooks)
Now , half of my new users are registered/imported and login through a "Facebook Login" button .
If someday ubb opens http-based API , I'd be glad to apply it and open it ... before I lose patience...
UBB evolves too slow ...
