So not sure how many of you on here do a lot of multiplayer gaming online. But teamspeak is by far one of the more popular methods of communicating on games, and has stayed strong for many years.
But would it not also be a great way to communicate, help each other and be social whilst developing games also? People might even pull together, and decide to model a load of statics between them over a weekend to make a unique looking level.
Personally I think forums have a place, but they are more formal, and less friendly then directly chatting.
Quote: "TeamSpeak
TeamSpeak is proprietary voice-over-Internet Protocol (VoIP) software that allows computer users to speak on a chat channel with fellow computer users, much like a telephone conference call. A TeamSpeak user will often wear a headset with an integrated microphone."
