How do I set up a generic user registration?

Here is my scenario:

I want to have a page that people (viewers) have to register to see. But I don’t want them to have to register everytime to see the same page...So I would like to set up a registration that requires users to create a username and password for themselves, so they can "log in" and view the page. I DON’T want them to be able to see any of the /manager or backend things in MODx...So I would need to somehow store and check registered users when they want to view a certain page.

Does this make sense? I didn’t see a snippet out there, and I’m not even sure if this is possible. But, any ideas or thoughts would be MOST helpful because right now I’m clueless.

Thanks and Cheers!

There is the generic WebSignup snippet included with the MODx core. I believe this is what you are looking for.
