When combining threads (particularly those which span several years), it's important to indicate where one ends and the next begins, and how they fit together chronologically; I've noticed quite a few where people (including me) now appear to be repeating information already given, whereas in fact we provided it first. The sequence of any discussion involved is as a result rather screwed up. I agree that it's a good idea to consolidate information available in threads here, but it does need to be done very carefully in order to be sure that it makes sense.
