Giving users a 15-minute window to edit their posts?

[MarkDavid]

I have noticed on other forums that when a post is made, the user has 15 minutes in which to edit it to fix typos and grammatical problems, after which, they no longer have the ability to edit.

I am having a problem with members going back and deleting their entire posts. I still want my members to be able to edit, but I don't want them to have the opportunity to edit posts made hours or days later.

So I would like to give them 15-minutes to edit their posts. Is there a way to do this easily?

Thanks!
