Is it possible to disable certain user roles from creating tags?

As a site admin, I’d like to have control over things.

I’d like to prevent my contributors and authors ( who generate content for me ) from creating new tags. I don’t want that tag taxonomy to turn into a zoo! Especially when you know that wordpress creates separate terms for apple and Apple! I give them a while list ( of 1000 tags that I want them to cover ) and that’s it. They cannot come up with the 1001st.

How do I achieve that so that my authors just pick from what I give them?

Simply change “administrator” to whatever you need.
