5 Facebook Applications to Add Useful Tabs to Your Facebook Fan Page
The applications are:
1. Static FBML - basically html for Facebook
2. FAQ tab
3. Youtube Video (Channel) - this one requires a name, email, and phone number so maybe not one to trust.
5. Contact form
I think the names of the applications alone will give you a good idea why they'd be useful.
Anyone using any of these or similar applications?
