Discussion posts are being routinely duplicated.
I've heard several people complain of duplicate posts lately.
I thought the programmers made some big changes to the forum code recently and by the many reports I have seen they have introduced more bugs than they cleared up.
Maybe it's because as soon as you publish a new post, there's an "error 404" page, so people think that their post wasn't posted and make another one. At least that's what I did, but then I saw my two posts and deleted one.
(this has been the case for me. I don't know if others are having the same problem.)
