There is a nice an easy way of allowing access of a page to people in certain groups, but on a site I'm working on I've got a case where I want to put a few members in to a new group, and give them access to a few extra pages, and hide a few page from them.

So, I needed a way of creating a list in the page called 'Hide Page From', where we could select groups. I achieved this pretty easily by overriding the canview() function, but I was wondering, is this a common enough situation to be built into the core?

By default I don't think there is a way to explicitly deny members/groups/roles. The permissions system is additive, and so far as I know doesn't allow for exclusionary exceptions. Perhaps that's a good idea for a module! (although may need some core edits to cms...)

Hi, yes, it's probably something I could modulize... (modulificate... make into a module)
