How to add the 'login and register' system ?

Hi There,

Unfortunately we don't have a member register 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 please be patient while we work on this.

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 with this tutorial: Adding Google Friend Connect

Please let us know if this service meets your needs or if you have additional requirements as this will help inform our planning.
