Limit selectable categories?

Hey all, I have a quick question that I jut can’t find a solution to.

I run https://www.DQGaming.com and I allow all of my users to post reviews on items they wish.

Now I have a few categories that I want only me to be able to add to certain posts. I do NOT want these posts to be marked private or anything like that. I just don’t want the average user to be able to put their post in the category.

Every search I come up with usually ends up just making that category as private for all other users.

One searched turned up a plugin called “Limit Categories” which actually seemed to do exactly what I wanted but it is VERY out-dated (2006?) and I can’t even find a download to test it anyways.

Any suggestion out there?
