Mr. Shannon, Thanks for your thoughtful reply. YES, there are quite a few good ways to collect solutions to each posted problems as you listed. And I do understand that if a thread is not updated recently, it will be pushed to the back. Maybe, Mr. administrator (who are they?) can chime in and let us know if we can have a few (just a good few) information collecting threads always stay upfront.

Here is a few suggestions:
1. What cured what
2. PNs (I compiled PNs for my 91 745T and 93 245)
3. what else?

At the end of the day, I might just realized that I'm being too silly. But that's OK.
