It just shows how immature the developers are.
Also if you want to add friends it is a hassle too. You'd have to type in the exact name of the player, it your friends name is long and hard to remember you can forget about it.
The correct way it should be done is, display all of the online players names and if the list is too long I'd should only need to type the first letter and it would search it for me.
So if Crysis 2 developers are reading it's about time you come up with a new patch.
