Please don't give up. I thought all the filter cutting postings were interesting.
I don't have any to post, because every filter I've got now is a cartridge, and they all looked just fine when I've pulled them out. The UOAs support the filter observations....or is it the other way around?
If I've been remiss in commenting, or supporting your efforts, I'm sorry.
Look at how many people have seen your threads - they were all interested in your efforts. Compare that number with the number of negative comments - you've got your troll percentage right there...and it's pretty small...
For example, this thread has been seen by over 1200 folks...how many trolls so far?
Cheers,
