a question....1st 2 answer gets props(if i figure how @ give one xD)

The easiest way is to post on someone's Стена and while you're Письмо the post there will be 2 buttons at the bottom of the Письмо space. One is for your mood and the other is to give a prop. click that and choose your prop!
It's that easy! Good luck. :D

Go to one's wall. Then act like Ты are giving a comment. Find the two things that Ты can click on. The first lets Ты insert an emoticon and the секунда lets Ты click and insert a prop. Your welcome!
