Time limit for editing a post

First I want to say I tried searching, but maybe I did not use the right keywords, so sorry if there all ready is a post about this.

Is it possible to put a time limit on editing posts? Like the user will have a 12 hour window with the possibility to edit ones post, but after that the post will not be editable (did I spell that right? I did not mean that it can not be eaten anymore )? I've had the problem with "angry" users that go in and remove their posts and ruin the flow in some threads, and I don't want that to happen again. But I don't want to remove the possibility of editing all together, I would just like to limit it to a window.

Does anybody know how to do that? Is it possible? I know it is on other forums, but maybe I need to upgrade or something?

General>Messages and Emails>Configuration
Post edit duration limit for a member :
Change it there
Save.

Oh wow! I missed that one! Thank you!!

Since this thread is marked solved, I will archive this thread.
