Hey @papalazarou74, Έλληνας και φρέσκος φρέσκος στο steemit?
Welcome! If you're interested in science, you can check out the @steemstem community project. You will find lots of great posts and authors under the #steemstem tag.
The greek community has also an official account, @greek-trail. You will see plenty of posts from greek steemians resteemed there or you can simply check the #greek-trail tag.
Enjoy your steemit experience! :)
I have just had a look and it's great. Thanks very much.
