Try acting like a new person in an old forum. Especially an old forum that tells you it is full of grumpy people who are dubious of new people. Don't post lengthy dissertations teaching us things. Don't claim to know how every business in the entire world operates. Don't try to impress us with your background in music or engineering or whatever the fuck. Don't post and post and post and not take hints. And don't call Birgir "Spritz." That is just stupid.
Take a breath and lay back occasionally and maybe you will find a niche here. Obviously, there is plenty for you here, and you are clearly enamored with the technical expertise that is shared here. But if you simply cannot filter and cannot help but sound pompous, then you're going to get this same treatment until you are banned or bail out.
