Private posts?

I have just installed WordPress 2.02 and got it working. However, I need a feature on the site that is not supported “out of the box”. this is the ability to make a user level, so that only allowed people can view certain posts.

This is so that I can keep some parts of my blog for only a few allowed people.

After doing some research, everyone recommended me wordpress, and told me that i could do what i wanted with plugins.

I installed wordpress, and installed the plugins but they didn’t work – caused loads of .php errors. When i did some more research I discovered that these plugins dont work with version 2.02 🙁

Is there any way i can do this with version 2.02? Or is this program just not suitable for my needs?
