When a comment has clearly been double posted by accident that's not an invitation to make a snarky comment.

You get "dead" on a dupe submit (happens periodically with me - not sure why) - not just down voting.

Huh, I didn't know that. Thanks.

I have had it happen when hitting the reply button gives you "expired link". If you refresh the page, then post, you will notice that the first post actually took, and the second one is marked dead.
