Hey people! My name is Andrew, I sometimes repair some sort of electronics. I'm from Donetsk, 3 years ago it was a city on the east of Ukraine, but now... You know if you watch news, but this place ios not about social news and politics, I think. I don't even know how I missed to register here before, but now time has come. So I here and waiting for a completing activation. For now - I think no reason to write anywhere else because just need some pictures from one thread, but, maybe later?
