I know that feeling bro. When I was Newbie on Bitcointalk (but not new in Bitcoin world and had not that bad knowledge) I was afraid to post because I worried that old users will eat my for a breakfast if I will say something wrong. Now it looks strange, but I though that I will say something incorrect that I can get ban. So, then I mainly posted in off-topic board. But when I got some good replies from senior and hero members I realized that Bitcointalk is beginner friendly community. Now I think that attitude towards newbies changed a bit because many of us understand that these people came here to make easy money.
The patience you need as a newbie account member, the 360 seconds wait to post. I think bitcointalk teaches you a lot of patience other than give you knowledge about the crypto world.
Yeah, when I was newbie I didn't liked that 360 seconds limit between posts. But actually, to make good post we need to spend more than 6 minutes
