I just don't get it how is that they don't understand that they really impair the growth by not having cross-account chatrooms... We switched from Skype to HipChat for our internal company communications, but we still use Skype for chats with all the clients. IF only I could tell them to create an account so we can chat... ugh. And no, I can't just give them access to our account, we have plenty of open rooms that should still be company-only.
