Request for Plugin.

Hi all,

There is a requirement, I want the plugin where the Registered users can post an Articles from the front end.

That Articles should be Managed by Admin, Only if the Article approved by admin, It should display.

I have used this plugin http://wordpress.org/extend/plugins/article-directory Which is not that user friendly, Can anyone suggest me with some other plugin which supports my requirements ???

P.S: I stand last in the Coding(Programming) point it will be really helpful if you suggest me with a plugin which satisfy my requirement

Thanks
Harsha.
