CMS CMS Permssions- Create Content- comments vs articles- choosing 1 only
 

I have it enabled for members to create content (but not publish).

For one particular usergroup A- I would like them to be able to add comments to existing articles, but not Create Articles.

However, if uncheck "Create" content in the CMS Permission- that usergroup can View the Comment Box on the page, but a Comment Won't actually submit.

If I check "create content" in the CMS permission for that usergroup- they can successfully add comments and ALSO Add Articles.

How do I set the permissions for Usergroup A to be able to successfully add Comments to existing articles, but NOT Create New Articles?
