Please check what happen to the Chat feature in v. Beta 1.0.6 - I cannot see how to send the first PM/Chat message - how to start a new conversation with a new user (case where there is no previous PM/Chat conversation with that user).
It would be good to improve the Chat welcome screen for a new joiner (the user cannot select any user or start a new conversation from the Chat screen yet.
But when there are no chats/PMs at all it looks "funny". Maybe we can have any welcome screen there. Also maybe it would be nice to get somehow the first message from the Space Admin/Manager to welcome user in PM (not sure if the Admin wants to get any messages from all new joiners etc but still).
