Member group help - limit access

I have a very active forum, but have recently had a problem with trolls.

What I'd like to do is create a group called "Innactive Members" and then somehow alter the permissions of that group so they can only view the Welcome board and nothing else. Then all members who haven't posted or logged in for 3 months get put into that group!!!!

Is there a way I can do this?

Thanks

Hello,

You can create a group from Admin CP > Users & Groups > Group Admin.
You can set permission in General > Categories & Forums > Forum Permissions Control

But, you have to add inactive members to the group manually, it can't be done automatically.

Thankyou.
