Have any of you guys tried using the Woobox app on your Facebook page?
The 'Free' version seems to allow better control of tabs, creation of HTML pages on Facebook and the easy creation of pages that require the user to click Like before continuing...
For extra money ($29/month) you can obtain email address from the users...
It looks fairly promising to us - it's the first such FB app we've looked at(!)
Any other suggestions?
