Boogy-
Ok, my apologies for perhaps misreading your OP. I am more inclined now to believe you are for real, and not trolling. Try to realize, however, that we are a generally helpful group, but also a jittery group. For probably most of us our only hope of finally becoming smoke-free is under considerable threat from the powers that be. There are many well-funded and vested interests trying to shut this whole industry down in the US. this is an open forum, but this whole culture is very uncertain of its future, and we are constantly anticipating another crazy and stupid attack. We have certainly had trolls here, and possibly worse, trying to divide and scare us. So when we are suspicious initially because things are stated in what we perceive is a strange manner, and details do not go along with patterns of the majority here, try not to think of it as attacking you, but rather simply security. Fact: many people pay attention to this board for malevolent reasons. Indeed, you should HOPE that we would be suspicious of strangers that come across initially as trouble, regardless of your actual intentions, which I now think are innocent. But this doesn't detract from the discomfort you likely felt. there are a lot of similar boards out there, although few better than ECF, and you could have just said f-you and gone off elsewhere to get info...but you didn't, and you offered information, and were polite and very civil...and some of us could cut back on the nic and try not to be so cranky. Suspicious is fine, but being insulting is not.
So welcome!

Read, search, learn, ask when its confusing, help others when you can, but realize you are being watched, and not just by us, and not always for the same reasons or the same ends. people here can be pretty jumpy, largely because of where they are psychologically and physically. Vaping does not replace all of smoking, and there is more chemical and physical addiction to analogs than just nicotine. Most of us are extremely happy to have either quit or rapidly reduce our tobacco habit, but we also find ourselves in a very new, very different, very wonderful, and very threatened place, and we are therefore a very protective bunch. There will always be the vague one-liner off-the-cuff people...seems to be ubiquitous to all forums.
As for PG, I personally do not like the stuff a lot. I don't like how it makes me feel, sort of headachy and stuffy, and I know that anything the gives a response like those in the short term is likely not good for the long term, so I prefer VG only vaping. I find it to be a cleaner vape that allows more flavor in mixes, and lots of great vapor. And in general people are more likely to have negative reactions to PG than to VG.
With respect to mixing your own, which I highly recommend, not just for the great juices you can make, but it keeps you physically involved and not smoking, I would recommend Ritalee's vid

There is also a spreadsheet available, although I don't recall the creator of it:
(Hope it attached!)
Much info here, many differing opinions, lots of tips. Immerse in it all for a bit. There is much to be found here.
Peace
