A request: could we have some advance notice of such tag merges in the future? If I'd known, I would have made the case that home-wiring and wiring are better synonyms. To my mind, wiring applies to the wires themselves -- installing, repairing, etc. -- whereas electrical applies to their use to carry electrical power, data signals, audio signals, etc. (I admit it's a fine distinction).
Have other tags been merged and/or black-listed recently, and is there a way for us regular users to see these merges and black-listings?
