Hi, and welcome. Just poke around a bit (new member information is a great place to start). There is tons of info on all sorts of vaping-related matters, but you can certainly start with any questions in the new members forum, that's what it is here for (besides being a place to welcome you to the board).
The support and what I learned on ECF was really REALLY helpful as I transitioned from vaping to smoking. You will also probably find your "happy social" places if you are seeking them in areas such as the Lounge, etc.
Welcome!
Anna
