To Edit cut off for 1 usergroup?

[Noctavia]

Hello...

I did a search to see if there was perhaps a MOD that could do what I want, but I couldn't seem to find one. I currently have a 12 hour time limit on being able to edit threads as some people like to stir up trouble and then come back and edit out all their posts with a "nm" when they have a tantrum (or see the argument isn't going their way...)

I've had a couple of members come forward with ideas about updating and maintaining certain threads (which I am very very happy about!) but of course, after the 12 hours, they can not edit their first post to make any updates. Is there a way for one usergroup (besides making them Admins or Mods because I only want them to have control over their posts) that will let them over right the forum time limit?

Basically I'd like a usergroup (or MOD) that will allow me to move a couple of users into it, so they can edit their threads indefinitely?
