Membership Wordpress Plugin

Hey guys. I'm having difficulty with a pretty simple task. I've made a site with WP, a static site. No blog component. I want to add a membership form, that they have to fill in and it signs them up as a user and the admin gets all the info they filled in related to their business. They don't get any privileges on the site, additional to a visitor. Any plugin or way of doing this?

I don't know,why you'd wanna sign them up.Getting a form filled up and routing it your mail dashboard would do the job.Still if you need membership types,i would suggest WP-Members is good plugin for the same use OR s2 member etc.But they are high weighed plugins,So my suggestion would be a fill up form or a custom made php function to add up into your site.

You can try paid membership pro. There's a free version and few additional interesting addons. This plugin also has great docs and video tutorials, so, there won't be any usage problems.
