welcome
i'm new too so i have some fresh perspective sort to speak.
If you already tried it out and it tasty nasty its because there is some primer on it when it comes straight from the factory that you need burn
through or clean off there are some guides on that as well. I didn't know about it when i started and just smoked
through it.
I would say the very first thing to learn (after you figure out how to operate it) would be the inhalation method then you can start figuring out how to refill, drip etc.
a really good place to look for info is the
EFC library if you go back to the main site here its listed.
There a guide to the inhalation method as well as good info on a lot of things for starting out.
Don't get overwhelmed but the amount of info out there. And there is a very long learning curve so you have to be patient and stick with it but its well worth it. I'm still figuring things out myself.
