Reading and writing comments is the way to go, especially for a Newbie without mich voting power. And while a big vote on a post is nice, reading a good comment and engaging with commenters is nice, too. Votes go to your wallet, comments go to your heart ;)
A tip for those who know another language than English: use it. Even if you just put a summary in that language at the end of the post or something like that. There probably is a #tag for the language - use it. And there probably is at least one discord server - use it.
Regarding your name on Discord: you can select different names for different servers. Just klick on the round server image on the left side (or press for some time on the mobile version).
