mod to limit # new threads usergroup can post?

[RobFerrari]

with all the classified ad mods that came and went over the years I finally just decided to make my classifieds forum based. with standard config I can set usergroups view, reply, and new thread permissions. however, I would like to limit the number of new threads a usergroup can create in a subforum per time period (1 year or subscription length).

does anyone know any mods that can accomplish this or something similar? thank you.

I see there is an older mod, would this still work on 3.8? any new similar mods? thanks.
