how do you friend people? plz answer asap.

If you're talking about befriending people in-game then I'm sorry to say but you can't as it was taken out of the game quite a while ago.

You can friend people over the forums still, all you have to do is navigate to...
User Control Panel » Friends & Foes

From there you will see a list. In this list you can type in usernames when once confirmed you will become friends with them via the forums. Alternatively you can check someone's profile and click on the 'Add Friend' link.

Note: This is only from your end and you will not be tagged as their friend unless they've gone through this process as well.
