Why in such a hurry to get your noob posts out of the way?
Use them to ask any questions you might have. You will get more (and often better) answers here than anywhere else on ecf.
Like many others, I'm sneaking up on 10,000 posts, and answering questions here.
OP, your njoy is an entry level device, and it must have done it's job because you are now investigating what is possible with these things. So I'll just say that there are now more choices with e-cigs than you ever had with conventional cigarettes. There are all kinds of different PVs and delivery devices, and thousands of different flavors of e-liquid. Only you can decide which you like best.
Most start out wanting an e-cig that tastes just like their favorite cigarette (myself included), but we quickly find that there are other flavors that taste sooooooooooooo much better. We find that we can make that throat hit stronger or softer depending on our mood. We can make vapor clouds that you can hide behind if that fits our mood, and we can play with flavors as it fits our fancy.
So jump in and get your feet wet!
