Looking for a custom hack

[LadyBeth]

I'm looking for a custom hack - I want to be able to keep a global setting I have which limits how long a user can edit a post, but I want to create a user group that all they can do is go in and manually remove their own post content. I do not want them to do anything else. But, the problem is the global settings seem to override this, in other words I can't have this special group and have a time limit on editing for my other groups. I'm looking for a hack that will allow my other groups to be defined as they are, but will allow users of this one specific group to do exactly what I set them to do, edit out their posts.

Please.... pretty please....:confused:I really need this....:confused:
