Due to limitations we are quickly reaching, we will no longer be allowing groups to create ranks that are outside of their internal structure. This includes group ranks like "friends" and etc. You may notice that the command /groupmembers frequently crashes, this is as a result of those limits.
Now, you may be thinking: But wait!? I use those ranks to let other friendly groups use our vehicles.
Awesome. My initial response to this was... great then they can join your group formally. My next reaction decided to be a little nicer. We will release a new system for groups that lets you create and manage relationships between groups. These relationships will be more in depth than they are now. These will be "allies", "mutual", "enemy". This is independent from the declaring war status. Groups with the allies status will be able use your vehicles, if you permit them.
