Each profile now has its own GuestBook system, so you can leave all your Battlecity friends or enemies a little message each time you visit their profile.

A Private Messaging system has also been added, which allows you to easily communicate privately with anybody you like. Take advantage of your profile to build a list of connections, because these players will then appear as contacts within your Private Messaging system allowing you to easily keep in touch. The system also allows you to block users, so you can prevent yourself from being spammed.
