I think a "InviteToTeam" request could be useful, so that the team owner can actually invite people in (I plan to create chat rooms based on the team mechanic).
I'll code my own for now, but think it could be nice & quick addition to the existing API.
In the same topic, unless I am mistaking there is no message to notify the team that a new member just joined/left.
That is a bit weird isn't it?
I can deal with it using script message. But ideally those messages should be provided (and we should be able to define our own messages, the same way we define our own EventRequest)
