Eric,
Hi!! I know you from at least a couple of other web-sites. Welcome to Rebreather World. This site has rapidly become THE site for rebreather pilots of all types and stripes. We have folks who dive rebreathers that aren't even known in the world!!
The thing that is making this site so good is the strength of our membership; their expertise, their experience, and the fact that they are willing to share that information in a friendly way!
We have our occasional spirited bun-fight, as our Brits are wont to say, but even those are well-tempered, friendly, and even-handed discussions.
Again, welcome aboard. Read our articles, ask as many questions as you want, and enjoy. We are glad that you have chosen to come to the "Dark Side" of diving, young Jedi!
Rob Davie
