Id say that we should consider to use Discord as Xernicus mentioned, that way we could even think of lowering expences TS is bringing to community. I have been playing with discord now for sometime, and i think we should give some gredit as trying it out to Achilleus whos been setting things up there. There we could have voice and chats unified in 1 app, and with correct settings there, importing users to channel is matter of seconds. There we wouldnt need any passwords to voice chats, we would get working app for many different platforms, and we could have more mobile way to communicate on the go between different groups.
These are just my 2 cents.
