Not really trolling. You can't come out and say something like that, which could be potentially be very beneficial for troubleshooting mpg issues, and not follow up.
I don't know what kind of forum etiquette you follow, but if I did a tech write-up (across one of the many forums I'm apart of) and figured out a way to make it faster, simpler, easier on everyone, but didn't follow up, that's just poor forum etiquette.
Small example...I figured out how to re adjust the front doors without taking anything apart (except the inside trim piece by the kick panel). I could have started a thread and said, "I re adjusted my front doors without removing anything!" And left it at that. Poor forum etiquette IMO. But I didn't do that and followed through with a write up with photos. Now, no one may have cared as it's not maybe a very common thing people care about, but obviously the thread he started has gandered a LOT of interest amongst the community.
