Plugin that asks to visitors to subscribe/register to view a page?

Hi all,

I’m trying to find a plugin that I can use to faciliate a members-only page on my site. I would like only “members” to be able to access this page, so I guess I need a plugin that would a) allow people to sign up to be a member and b) log in as a member to see the restricted page.

Does anyone know of a free plugin that does this type of thing, or am I stuck with Member Wing, etc.?

Thanks!
