I found this but can't find buddy list on my profile.

Buddy List
The Buddy List section of the profile gives you the ability to add other members that you're frequently contact to a list that will show in your User CP view. Your Buddy List will display each name, their Online/Offline status, and link options to send the user a PM, an e-mail, or visit the link to their website.
Add users to your Buddy List by clicking on the link below the Buddy List display box.
Delete users from your Buddy List by double-clicking on their user name inside the Buddy List display box.
