37395 Membership Website

I want to create several Free MEMBERSHIP websites. I need a script that will be easy to use that on the main page someone can will enter a desired username - password - their name and email. The catch is that I use Awebber as my autoresponder and I want it to subscribe them to my autoresponder along with the members site. I would like to have a members login page that will be emailed to them along with their username and password after confirming their opt-in?? Would like to be able to control myself when set up - ?? Create the forms etc. login pages etc. I use html for my web pages! I MAY want to do this on more than one site? Hope this makes sense. I can send pages where there is an example of what I need if you wish??
