Well, I found a solution in the SMF admin backup. Turns out you can set rather detailed permissions by membergroup or by board.

Members can no longer edit posts in the Dead Pile.
Any reason to remove the ability for members to delete their own posts? I suppose it doesn't matter since deleted posts are moved to the Dead Pile automatically now, so they aren't really lost.
Also, I would like to remind mods to be careful not to interfere to the point that you irritate others.
Inappropriate content should go to the Dead Pile, and perhaps multi-post threadjacks, but I don't delete posts where members are being silly or just clowning around. I noticed a few things in there that seemed innocent. Perhaps it was the members themselves deleting their own posts, but in the future, if you move something to the Dead Pile, please post a reason on the dead thread.
Thanks!
