Welcome aboard to Steemit. I'm @gungho because I'm gungho on every aspect of cryptocurrency and I also enjoy blogging! I'm a female, so don't be confused about my username. To join a community that helps support your posts, you can click on the top left steemit logo, and you will see a box of communities on the left. You can just scroll through and find the ones you would like to join and then subscribe. Then, when you post, post in THAT community. People in that community can help you get started by supporting your posts. That's how is basically works here. I'm glad you are here on Steemit. See you soon~^^
