First, thank you all for your quality feedback. We’re working hard (not just hardly) on the next update and are aiming to make the new version available in the course of the next week, unless critical issues are encountered. Fingers crossed. 
We apologize for any inconvenience the chat system outage might cause.
To answer some of your questions…
Based on your statement, we assume that you’ll be pleased with what we have in stock.
Starting next week, we’ll continue to provide hosted chat services for all beta testers. So no need to set up your own camp.
Yes, you will still be able to share messages without being connected to a TeamSpeak Server.
We hope that this answers some of your most important questions.
