but cant you add it as one of those features where you have to place an x amount of posts to be able to view it (along with others, like a users website if im not mistaken)?
Why would you need to view the member's list anyway? If you want to email someone, you can pm them and if they want to continue talking to you through email, they can give you their address themselves. I have done that with a couple of people. I doubt I would want just anyone viewing my personal information.
