Welcome Nick! Don’t worry about making mistakes. There are none here. Just be yourself and get involved. Reach out to people that post on a topic you like and engage them. Start and open a dialogue. Post original content. Stick with it. Even when it looks like you are getting nowhere...tough through it. Build your audience and following. It’ll come if you put the effort forth. Best of luck to ya.
