Have posted / not in x days (filter out users who only read and don't contribute so can use it for limit their access globally)
Same as above but with selectable subforum (so can revoke permission for this subforum completely)
With a Member base of ~ 10k it is hard to track it.
Till now i use an addon for this but for some reasons sometimes it work and sometimes not.
Not clear why. Is no scheme to see.
So would like to see this in core.
