Wizard, she did post an apology about it. Go check on the thread. I also lost a thread a couple days ago when I tried to delete a duplicate. I'm not sure what's going on yet, but it wasn't intentional in either case.
Please don't assume that we wander around here deleting posts we don't agree with. If I did that, I wouldn't have time for anything else! *grin* We do, however, delete accidental or intentional duplicates, and, unfortunately, at the moment, this seems to be clobbering the entire thread from the duplicate post on down. The problem is being looked into, and we won't delete any more duplicate replies (or anything else, so, trolls, have your way with us for a bit!) until the problem is addressed.
