I wanted to offer users a demo account, eg login with user: test, password: test, but I have features like email forwarding. There doesn't seem to be any way to disable features like this on a user by user basis.
On kind of the same note, what about if the user wants to remove ads, an include file could display ads, be removed per users that pay, instead of trying to set their default template? Is this a plan for ver 3.x.x
