Hello @kenji3, I am very happy to welcome you to the steemit site. I appreciate your interest and effort but you have to learn a lot about the steemit site first. Definitely visit this Guilines Post and read it once and you should first post your introduction post in the Newcomers' Community community. Once they approve you, you can start posting in other communities. I wish you to grow further in steemit and at the same time we expect quality posts. Feel free to contact me on discord for further help
