Vostok you are a very busy person. I wish I was an expert at something. I know more about Star Wars than the average Joe, but I am not an expert. I can hold my own in these forums though and I have given most folks here good run for their proverbial money. I still have much to learn, but I have found that I am full of surprises. Sometimes, I've even amazed myself.
Do you guys ever do that? Sneak in lines from Star Wars into a conversation just to see if the person notices? I do it to my wife and kids all of the time and it drives them nuts.
Anyway, sorry for getting sidetracked there. Being an "expert" and well versed in a subject are two very different tings but are both to be commended I think. I there are fields of study that one enjoys then I say spend time in them and pursue them and share your knowledge with others, that's why you make the time for those areas.
Good job Vostok, way to go.
Besides, it's not bragging if it's the truth.
Go big or go home.
