Juan,
Very impressive, you should write up how this is done, as I can see how I could customise the page of a local school if this were - say - Frontpage, but I have no clue being a 'newbie' PHP user.
Following on from a previous post, I'd agree with the comment that schools really would like to preserve their identity, and the ability to adjust the theme is a vehicle to provide that common look and feel between the LMS (VLC) and the school Website for example.
Any suggestions - tutorials - working examples?
