Back in the 90s I was still working in the field and there was a lot I didn't know. Luckily my local Inspector was a Great Guy and if he wasn't busy or out in the field I could sit down with him and he'd explain or answer any questions I had. At that time there was really nowhere else to go. I didn't think My local ECs were about to help out their competition (Me).
I thought it would be great if there was a place to ask questions semi-anonymously without feeling stupid and others would help without worrying about losing work to other local ECs. I had access to some Business Conference software (which I was told cost $10k at the time) and the first ECN 'Forum' was born.
It was pretty slow going for awhile. I don't remember the first post, but I remember the second... (or might've been an email) I believe it was Bjarney, asking why
I didn't answer the question.
So, I explained to him I wasn't necessarily a qualified source of info on the subject and was trying to get dialog going between others. He got it and was a valuable contributor for years after.
