member ship plugins for wordpress

more complex and full of features  is http://wordpress.org/extend/plugins/wp-members/, but difficult to adapt

wordpress post / page save and see

After a few hours of searching on the internet I finally assembled the hooks and actions necessary to add a new button to the save meta box for worpdress posts and pages.

Hey who's making the plugin ?
