How do I register users for access to a page on my site

[Land Man]

I want users to register with a user id (their e-mail address) and password
to gain access to a link on my page. I then need access to that information
and how to make sure that when they register they have access from then on.

The best way to do this is with server-side scripting (such as ASP, ASP.NET
etc) and a database. You would set up a registration form on the site.
Users would fill it in and the information inserted into the database. Then
when they return they would login in and your page would authenticate them
against the database. See the example at
