Contacting Other Teams

Is there any way I can contact other teams? Is there like an IM etc.
Definitely something the game needs
Nothing that I am aware of so far, but a great idea.

In the meantime, on our guild page, you will see we have added an email address
Britishlions@btinternet.com

Best we could come up with until a solution is found
can you not use line ap for contacting people?
