Will cause bedlam in FS FT I would have thought as you can edit in a higher value offer if you get a rival bid. I don't think I'm the only one to have thought of this - its buried in a few of the "report bugs here" - however I am not sure it is a bug.
Hence I wondered if it was a tempory glitch, or permanent? If so could edit post be disabled for the FS FT board (and possibly allowed through Fo.lk if that shows edit times)
