Jules,
Welcome to Rebreather World!
We like small and noisy

feel free to chime in anytime

As far as the phrase goes that you are looking for, I belive it is refered to "lurking" or something along those lines....
Anyway, that sure is fine to just read around and wet your appetite of diving a rebreather. RBs are great for diving in the Galapagos..... I just had to write that
Well, look around, read as much as you can about RBs, don't hesitate to ask questions, plenty of friendly Rebreather folks here who are willing to help. And maybe sooner than later try one of those rigs out, just to see how it feels.
Again, welcome on board!
cheers,
RBN
