Several times recently I have gone to look in my profile at my own posts, to see if there are any responses on a thread I had previously read and responded on, only to find that my response is not listed. The first time I thought "Huh, that's strange", the second time I was a little more puzzled. Today I looked for a particular post that I know exactly when I posted and it is just not there. I remembered a key word in the thread and searched on it. The thread came up in the search results but when I clicked on it, I got the "bad request" message. I read Nifty's explanation for why chat was taken down, which was that when someone posts in the forum it is there "forever" yet it seems that these are threads that have been deleted. I thought threads were just closed to new posts, not deleted, but now I'm starting to wonder. What's going on?
