The Hobbes list recently had a thread called something like "Thing's Captains say" which illustrated some of the many means of communicating. I wouldn't recommend entering into the fray right now as there is a bit of turmoil, but the archives have a good deal of useful information whether applicable now or just to gain a perspective on the tandem life style.
The most important word in your vocabulary has now become "sorry" which was immediately preceded by failure to use the second most important word, "bump". Words for stopping, starting, cars, signaling, dogs, etc. are all there to be invented or copied. I'm sure MTB tandems have some phrases we roadies have never heard.
