I want to try to use open id as login system on the site that I am going to make. I've check out this site, and I'm not pretty sure how this all works and how to make it work. http://remysharp.com/2007/12/21/how-to-integrate-openid-as-your-login-system/
What is clear right now is that open id uses urls instead of passwords. Can you give me some links to help me get started with this, Do I need to know advanced php to make this work for me. I only know the basics of php.
