Hi Ben,
Thanks for your post. We had a problem with the Cart this weekend, but it has since been resolved so you should now be able to purchase. Our apologies for the trouble there!
Do you have any screen shots of what the plug in looks like?
There are a couple screen shots on the products page. They show the two backend pages that the plugin adds. Since the plugin does not have any front-end use, there are no front end screenshots.
Can people sign up to the event on their site with their facebook page? And does it show the people who are coming and their facebook profiles?
At this time, these features are not part of our plugin. We are considering adding them in the future. Facebook Events is a simple plugin designed specifically to bring events from Facebook into The Events Calendar, but it does not add any other Facebook-like features.
Best,
Leah
