I just have to make this comparison, even though I may be comparing apples to oranges, but coming from an Amateur Radio background, I think that they are pretty easy going on the rankings in this forum. If this was Amateur Radio, every last one of us here would be "noobs". It takes five years of being a licensed "ham", before one qualifies for being an "Official Observer", ham radio's equivalent of a "Moderator". Also around five years to be considered a "Veteran" and if you want to be an "Old Timer", well.....that comes about after 25 years of being licensed.
Sun, I was an Army Veteran at the ripe old age of 21, so being a veteran, doesn't necessarily mean you are old.
Since e-cigs are so new, I guess anyone with over 2 years experience could be considered an "Old Timer".
