Is it possible to limit writing into some categories depending on user type?

Hello,

I'm changing a site from a magazine through com_content and a community blog in easyblog, to everything through easyblog (for easier use of the community created posts), but, not everyone should be able to write into the magazine...

I though best approach would be to make magazine categories (news, articles, interviews), but I've not managed to limit these depending ou user groups (only authours should be able to write there for example), and same for some other special categories (the idea is some entities have their own blog, posted in the magazine)

I'm not sure if this is the best aproach either... :/

The site is a village portal, and the idea is to have a magazine with everything that happens or is interesting for the village, also, entities (political parties, football team, school, scouts,...) should be able to have their own blog, and some of their posts published in magazine...

What you think should be best configuration?

Notice all categories should (by default) be viewable by all audience

Regards
