I believe that Icemod should form a Discord server. Its free, it has Twitch emote support through the use of an easy-to-install add-on, it looks more appealing than Team speak, has more organization for text and coice chats and is very customizable. Its really just and general upgrade from Teamspeak.
Discord seems flashy and cool on the cover, but it really isn't. It's latency is tremendous in comparison to what we can achieve with a teamspeak server, it provides very little tools for administration in comparison to teamspeak, and the client is a lot more resource intensive than teamspeak. Plus, their servers aren't exactly known for their excellent uptime.
