How to restrict users from specific categories? Need help

Hi there everyone,

Currently i run a Music review website where i publish all sorts of articles such as reviews, interviews & write-ups. What Id like to do is create a category for users to post in and only in that section. I do not want users to have access to other Categories that I am currently using for the site. So if there is a plugin that will allow me to prevent them from seeing other Categories and only allowing them to post in that category’s that i provide them with would be awesome!

I’m quite new to the forms though I’ve been an avid WordPress user for years. I’ve looked at quite a bit of plugins but couldn’t find exactly what i needed.

So if anyone can help me out by either sharing some information on where about’s i can find such a plugin or if i need to purchase one that would be much appreciated ??

Thanks
