Delete/Identify Group Proposals

I have a group with a lot of members. One of them has been continually posting Proposals of a slanderous nature. Is there a way to see who is creating these Proposals, to Eject them from the Group? For that matter, is there any way to delete a Proposal once it has been created?

If there isn't, is this something I can call Linden Labs about?

Thanks in advance.

Maybe you can set the roles up so that only certain members can make Group Proposals? It's just asking for trouble to let everyone make proposals. Regarding past proposals; I'm not sure what you can do.

Thanks Oryx, yeah, once I discovered that Everyone was set to be able to create them (it's a pretty old group, so maybe that was default or something back then), I turned it off. At least he won't be making any more! I also turned off the ability to vote, so maybe people who haven't logged in yet won't have to see it. That's all I think I can do for now. It expires one 10-2-08, but then it'll just move down to the past ones box. There's one in there from two summers ago, so I think they stick around.
