MyBB Community Forums

I'm working on a section for those who donate to the forum and for senior posters. How do I allow senior posters to view the forum whilst blocking lesser posters from viewing it?

Try this plugin: http://mods.mybb.com/view/forums-requirements

Thanks!

Doesn't quite suit me since I still want donors to be able to see the forum, even if they have less than a select number of posts.
