If you did any reading in the DIY section, you'd be amazed at how knowledgeable the people there are.
Some of those "Joe Schmo's" as you call them, down in DIY topic are pretty durn
gifted.
As a matter of fact, they were posting about certain inhalation risk chemicals that might be in ejuice 3-4+ years before any studies came out.
Many of the people in the DIY topics are better mixers than many of the vendors.....some have become vendors.......and some just don't want to actually go into business.
There were even some mixers who later became vendors that sought their advice down in those topics.
When you understand this, by reading there, you will see that probably a large number of folks down in DIY section could very well mix you up 3 "ADVs."
