I've read a few threads, and seen recommendations to search for a topic. I'd like to search for "Teamspeak", but I don't see where to initiate a search. The reason I want to learn about that is that I wish to try some casual multiplayer racing, and I found this in a thread about club racing: "As long as written chat isn't available the use of Teamspeak is mandatory. If you can't join our Teamspeak channel and stay in it for this event please sign out in time." How can I find out what this involves?
