I want to create logins for visitors to my site - how do I do that?

Unfortunately we don't have a member registation and login feature yet, but we hope to add it in future. We know that many people would like to have people register for accounts and have logins for their sites. We will need to do quite a bit of development to make this possible, so we can't make any commitments about if or when this feature will be released.

You can password protect pages (see a link to more information below).

This might not be quite what you had in mind, but you might want to try using Google Friend Connect. You can find information on how to add it to your site on this tutorial: Adding Google Friend Connect.
