Thread:Project:Support desk/Suggestions for ways to prevent new users from editing User Talk pages.

As a way of reducing spam, trolling, and vandalism, I'm looking for a way to prevent new users from editing user talk pages.

I have an idea for accomplishing this: I am thinking about creating a user group (for example, Frequent Users) and giving them the ability to edit user talk pages. Editing of user talk pages would be restricted from regular, new, users. When a new user has made a lot of contributions, and shown that they are interested in our website and being productive, they can be added to the user group that has the right to edit user talk pages.

I'm not totally sure on the exact set of instructions I would need to add for setting the user rights and user groups, so help and suggestions would be appreciated.

Would there be any way of allowing another user group (such as sysops) to add the Frequent User user group without having full user rights management?

If there's any better way of doing what I want to do (such as an extension), please let me know.
