Well, I have a question:  how to determine that someone has sent you a letter (I see no changes in the sidebar). So, pleace, send me a letter in order that I could see that the sidebar works (it didn't work in case if someone acceptes your friend request). Ou.. before sending me a letter you could read my blog (it's only two posts long - a young blog)) and write what do you think about my idea. Have a nice day.
