i want to suggest a thing about the

Access is forbidden

error message.... its not enough specific...and not inviting people to correct this missing requirement... first : why i dont have the permission? because im not a member or because the membership must be upgraded? the error message should say : you must be a registred member to access to this content.... or you must upgrade to premium membership to access to this content... (with a link to the signup section or upgrade section) so see more this way the user will know why he cant access to this area and will clearly know what he should do to be able to access it...
