I used to say "thank you", but on reflection decided that it might be interpreted by some as "f**K you", so now I try to smile, wave & just say "thanks".

I also use the right arm-right turn signal when riding by myself, but in groups it is sometimes suggested that right arm signals should be reserved for pointing out road hazards. Of course, if the hazard is to my left I use my left arm for them so I don't think of that as a hard and fast rule.
