Welcome on board :) There's a lot of people writing in different languages here so you'll be able to practice your polyglot skills as much as you like :D (I think that's so cool that you can do stuff like that, I'm so slow at language acquisition XD)
Super basic primer:
- have a browse through the tags for people that produce stuff you might be interested in and comment on any interesting looking posts they have
- see if your country (or whatever country you're writing in the language of at the time) has a team (sometimes they call themselves teamwhatever and sometimes it's steemwhatever and some have both) and use that tag
- there's also other groups you might like to get into like minnowsupport, thealliance, and several based around interest, though some of them might take slightly more work to get into
And most importantly enjoy what you're doing :D
