I'm in IT as well and I hear ya loud and clear. I have a Twitter account but never use it.
You are absolutely correct about this forum as opposed to others. It's always a bunch a jackholes fighting and insulting each other or disrespecting the newer members. Not here though. All I've found here so far is a bunch of friendly helpful people. I like this forum a lot.
Just one thing to watch out for when messing with the pg /vg ratio. The more vg ya use the thicker your juice will be so some equipment won't work as well with the thicker fluid. I think I saw some where that if you use mostly vg in a juice some of the ego-t atomizers won't work as well. I can't say for sure if it's true or not but just something to be aware of if you find your not getting your expected results.
I've found that adding 10% distilled water to my vg mixes does the trick.
