Last week I was playing around with some FBML and discovered that it’s really easy to add comments to a custom tab on your Facebook fan page. All you need is the page id and a little block of code.
The most difficult part of this is finding the page ID. It used to be in the page URL but ever since custom names for pages became available it’s a little harder to find. Of course, if you don’t have 25 fans yet or haven’t made a custom URL for your fan page, it will be easier to find the page ID.
