Well, I think the answer varies. In the case of command posts, they haven't really been called that since something like 2.0 or before, I just haven't updated the name. I'd say that one is still relevant, and just needs to be completely redone with the new expanded info, etc. Deleting it and just doing a new topic is fine, whichever. I don't really see any value in keeping around the pre-4.0 answers, as we're not supporting that anymore and having versioned info is just going to make this a nasty mess of outdated info even over time. In the case of strong vs and weak vs, there is no real counterpart to that page on the new 4.0 versions, so I just deleted it completely and left it at that.
