Thanks for your advice, but I was banned from mid Oct to mid Nov, so that does not explain it ... or why I was banned in the first place.
In response to "tcmtech's" post, no I didn't sign up again under a different account. This has always been my username. And if I got on "someone's bad side", I can't imagine how.
Frankly, I am afraid to post anything now since I don't know if it will be misinterpreted. If I go missing again, you will know why. A bit unexpected on an electronics forum.
