You will be able to get plenty of helpful advice from this website. Much general information for new users or those considering getting into vaping can be found by clicking on the above InfoZone link or here:

You need to pic up at least the basic lingo or terminology that people use here. It's not hard to learn, just be patient.

You'll soon need to decide which class of battery to begin with - either something that tries to look
like a cigarette or something that is just a little
bigger and longer but will perform much better and give better results.
Fact - the bigger the battery, the better the e-cig will perform in terms of battery life and vapor production.
Fact - e-cigs or PV's, obviously need a charged battery to vaporize the nicotine juice. The main difference between the mini's that are cigarette sized and the eGo's are the size of the rechargable batteries that they use.
Fact -
the main determining factor of which class of batteries that you decide to begin with is, "How important is it to you that your first batteries look eactly like a cigarette?"
The best place here to find general basic information is at the top of this page called "InfoZone." Many categories of info on that link, spend some time there to get aquanted with the lingo and terminology.

I'll make a couple of recommendations of product/companies for you to consider for your first vaping devices:
Cigarette lookalike or Mini-sized:
Smokeless Image | Only The Best Electronic Cigarette | Smokeless Image Electronic Cigarettes - The Future is in your hands
eGo intermediate-sized:
AltSmoke.com | Personal Vaporizers | Electronic Cigarette | Ecigs | Joye eGo Starter Kit
You don't have to order your kit from either of these two companies, but I list them as a starting point because I have used both because they carry high quality products, have excellent customer service and fast shipping, and they have earned many people's respect here at ECF as excellent companies to do business with.
Many postors will recommend an eGo Twist.
AltSmoke.com | Personal Vaporizers | Electronic Cigarette | Ecigs | AltSmoke.com | eGo-C Twist Battery It's a great battery that will provide you with
variable voltage, but as a beginner you don't really need it. If you can afford one, get one along with your beginner kit, or wait until you are more experienced to get one. Variable voltage is not for everyone.
Your focus now should be on getting at least two batteries/APV's and e-juice/nicotine liquid.
Both above companies sell nicotine liquids. These can be used either in pre-filled cartomizers (easiest for a beginner, but more expensive), or blank cartomizers (empty) that you fill yourself from bottles of flavored nicotine liquid. I'd recommend getting some sampler packs of juice to see which flavors you will like. Everyone's tastes are different, and they may change as you progress along. Therefore, don't buy large quantities of any flavor until you are certain that you like it.
