Hide Category for non-members

Hey fellow WordPress lovers!

I wanted to ask if anyone out there have a solution for my problem. I am building a CMS site and have a few members who contribute to the site. Some of them are new and never used WordPress, and all though we might think its easy to use, some people out there dont.

What I am looking for is to create a few pages, add them to a category (i.e. Help) and hide it from everyone except for those with higher roles then Subscribers.

So if your not logged in, or if you are but are only a Subscriber you can simply not see this category. But those who are higher does.

One solution I wanted to use was to use 2 widgets in my sidebar. One is a normal “list categories” and one is for members.

Any suggestions?
