This is much easier than using a third party app, because someone would make a group and then create a password. Only people with the password can get in. It would be great if you are the owner of a clan, because you can create a group and tell other owners the password to lay out war strategy, cf terms, another clan, etc.
Great idea and the password one is good too. But will they actually do somethin like that? Its unlikely.
It's crew chat. No password. Someone simply starts a crew and his/her friends join. The crew expires in 4 hrs
This kinda thing has been mentioned by Frankenstein in my thread. You can find a detailed description of his thoughts in the "side thoughts" of my thread.
