Be cool kids
dont break the rules
Facebook have spent a lot of time making such a great site, service and API. And because they have put so much in, they can set their own rules. myApi makes it simple to create an application for facebook, but in the process you need to agree to the facebook terms of service for applications. But don't worry myApi sticks to the rules, however there are some other facebook connect joomla components that rely on breaking these terms of service and not abiding to user privacy and the poiclies on storing personal data.
In short facebook will not allow you to gather information about a user, for example their first name, using their API and then store that information into you websites database. You can only store users information for a maximum of 24 hours, thats why myApi only stores the users facebook ID, and then caches their details for a maximum of 24 hours.
Do not use other joomla solutions that break the facebook terms of service and respect user privacy online with myApi.
