Searching for threads for series with common names such as House, or Lost etc can be a real pain in the ass. One idea would be to include a code word in the originating post XXYZ1 or whatever, which would allow a search to return all the threads fairly easily.
What I don’t like is when they specify them by date of US broadcast, as though that means anything at all many months later, or to people from other countries. Please use season and episode number, or episode title, as appropriate.
