A THREAD FOR NEWCOMERS!

You won't believe it, but there's text in Russian down there:

So, if your avatar is too large, you need to either crop it or reduce its size.

I cropped it and reduced it to 150 pixels, but it still doesn't work.

I asked about how to play online, and you provided a link to a place where people arrange games, but there's nothing about how to get started. Can you tell me about that or provide a link to where it's explained?
