You will want to add friends to your pal list. The pal list is on the left side of the main Paltalk window and shows everyone that you have added, and if they are online and offline.
Search for new pals
To search for new pals, click on the little magifying glass icon on the top of the pal list area. Start typing as much of their name as you know, then click on the 'search paltalk' button.
A list of possible matches will appear and you can click on the 'add' button to add anyone you like. When you are finished click on the 'X' near the top right of the pal list area.
From within a chat group
You can also add anyone you encounter in a group to your list of pals, or 'pal list'.
When in a chat group just right click on anyone's nickname and select 'Add as a Pal' from the drop down menu that appears. Thats it!
