Currently it's possible for the original poster to delete a complete post including all the responses.

Not only is this bad netiquette and detrimental to the knowledge-sharing philosophy of the forum. But it's also unfair that someone else is able to delete posts that are not theirs (except for of course the moderators). If anything, the original post should be deleted, but all the responses should remain intact. This became relevant to me, due to this forum post...

Is it possible to change the forum settings with regard to deletion of original posts and/or responses?
