How do I unsubscribe from emails and delete my account?

Hey guys, I accidentally created an account on a Russian site. I speak no Russian. None. I'd like to be removed from the constant emails I get every week, and better yet, to delete my account.

I've spent hours on this site trying to figure it out, but since I can't read Russian, it's quite hard. Can someone please give me instructions on how to do this?

Thanks!
