Welcome. I just picked my new COPIS Meg at the factory yesterday- start my training in November. There's tons of useful info on this site, but the bulk of the newer posts are about advanced CCR stuff, and minutia that doesn't concern us newbies too much. Start off in the library in the "New to rebreathers" section- this is a great place to start:
