Welcome Tamara, and greetings from your neighboring country (Austria)!

@theaustrianguy already mentioned it, but it doesn't hurt to say it twice: we run a science community on steem, called @steemstem. You're welcome to check out our post, to join our discord chat server for advice or just chatting and of course to write about science using our tag #steemstem, which we curate (i.e. we give quite big upvotes to well-written posts).

Also, should you want to learn more about the steemit ecosystem, you can check out this great newbie guide.

Have fun, and cya around!
