vkontakte (вконтакте)?

[Cole]

Hey so can someone help me with vk.

I made a Vk to because I am interested in Russian/ Ukrainian culture/ life and I wanted to talk to people who actually lived in Russia/ Ukraine (I live in the U.S.). But, I am a little confused.

First question: Can you message non friends? I messaged a lot of people, but the only ones who have answered are people who accepted my friend request.

Second question: On my message list, why do some messages have blue behind them and some have white?

Third Question: Does the person get a notification when they are invited as a friend?
