Meanwhile, look up @mitneb. I see she has already hooked you up! She is a great help to all minnows/new members, and specifically a good supporter and guide of those for whom English is not a native language. Here is an invite: https://discordapp.com/invite/jhEuJpJ, to her awesome discord where you will meet very many other awesome members and share experience, and support each other.
