I did a search to see if there was a thread for such things, couldn't find one though.
Personally, I've picked up a lot of useful hints and tricks on RetroBike. I also see a lot of threads where people are looking for advice. Could we have a thread dedicated to things we can do to help others with the knowledge we have learned over the years all in one place? Much like the How much is my XYZ worth thread.
