Cześć! Hello! Здравствуй!
I'm an admin of the Metro Wiki alongside Chaosian, Komo, Teddy Picker, and ChrisN34. I've been contributing since late 2012, but became an admin in early December of 2015. We do our best to maintain this wikia as the best English-language source of information for the whole Metro 2033 franchise, both the books and the games.
My native tongue is Polish, but I am also fluent in English, semi-fluent in Russian, and know a tiny bit of Finnish. Apart from adding general content and doing maintenance work, most of my editing interests on the Metro Wiki involve making Russian/Polish information available to English speakers (for example).
If you're wondering, my username "Karmazynowy Wilk" is pronounced "Karmazinoviy Vilk" (roll the R) - it's Polish for "Crimson Wolf". It is a name I used to go by in some other online communities, though I can't remember why I picked it or if it's a reference to anything in particular. It's a bit of a mouthful, especially for those not fluent in Slavic languages, so feel free to call me Bamul instead.
On a side-note, for anyone who is a fan of Eastern European post-apocalyptic stuff, I highly recommend THIS FILM. If you liked Metro 2033 and are a fan of Tarkovsky's work, then this forgotten classic of Polish cinema will probably be to your liking as well.
