member list???

i have searched for 10 days on a simple plugin that lists members on a website, so that my users can see who is on the site.. i have seen around 20 or 30 variations of this but nothing simple and basic, the other stuff is for the admin only?

is there no such plugin that a User can sign up on my site, click the members button and be taken to a list? a nice list with avatars and basic information? or just names linking to a profile? this seems like a very basic thing that would have been one of the first plugins made.
