how to make a wordpress user system

Hi Jon,

Do you mean a Wordpress membership site?

If so, I use Wishlist Member. It's a paid plugin and I've very happy with it. Did a lot of research and it had all the features I needed. In particular, it allows multiple payment gateways including Paypal, Clickbank and JVzoo.

There are also good free membership plugins out there.

Search the Plugins area on Wordpress.org

What kind of user system do you want, could you be more specific?
WordPress by design already has some system users integrated with the platform, and MANY free plugins are also available to even make it better with a lot of functions and possibilities, but that all depends on what you want to accomplish.

try Justin Tadlock's Member plugin...
I also like eMember for a premium solution.
