Welcome! Everything you need to know about this site should be listed in the Code of Conduct. Basically, don't post private information/off site contact information and be nice to everyone. There are a few more rules than that but those seem to be the big ones
Welcome to EC little Romandude. I'm new too. But, from what I gather, you just kinda post your problems and get advice and support or you could give it too. ^-^ Oh, and follow the rules blah blah blah that too.
