[How To?] set post limit

[BigTimeRush]

I have created a specific section where I want members to have atleast 60 posts and then they become able to post.

A member is having less then 60 posts, He gets error. He has 60 or more, He is able to post. Tell me how to do this without new usergroup.

[.m.]

if you want to restrict posting new threads then this plugin should help.
or may be above plugin can be modified to suit your requirement.
