Members Area

Hello

Wonder if anyone has had any experience with a members only area on a site;

Basically I want to create a member only area, imaginatively called ‘Members’ and any pages under that be only accessible after having logged in or registered, theres also a bbpres forum in there also;

So my questions are, is this possible? is there a way to create a subsection? and everything under there to be restricted to members? and use its own registration and login form.

Anyone had any experience with this?

Thanks
