Specific forum posting time limit

[Sferle]

Hello!

I've searched this forum and on the internet but I can't find how to modify the posting time limit of specific usergroups to post on an specific forum. I've only found mods for edit time limit.

I need to prevent some usergroups from posting, in an specific forum, before the given time limit... so they can post there only after 1-2-3 days.

Does anyone know how can I do this?
Thank you!

This' important... Anyone with an idea?

You would just create a new usergroup and then promote those users to that usergroup after x number of days being a member.
