Just a quick heads up for any developers and Fan Page owners. Facebook announced this way back in November in the developers roadmap and produced a slideshow detailing the changes that need to be implemented by Developers and Fan Page/Profile Owners in January (see below).

Basically it means from the 23rd of August if you use boxes on your fan page or Profile for data capture, apps etc they will no longer work. All content will need to be moved to the tabs (which should be pretty easy to do click edit page, click application settings on the box you want to move and select Tab (add) and Box (remove)). More importantly it will have an effect on custom FBML tabs as the width is changing from 760px to 520px.

See here for the latest update: http://developers.facebook.com/live_…ref=mf#msg_641

All IMVA cusotmers pages will be changed automatically with no additional charges. If you need help please do not hesitate to contact me.

Personally IMO it could have a big effect on the usability, design and interaction on a Facebook Page as it is almost like taking something away that worked really well. I guess only time will tell!  What do you think?
