Since I fit as neatly into the category of non-poster as anyone you will find, I can at least offer my reasons.
When I signed up here, I thought I was at a place in my life where I was going to have more time to participate. That was just wishful thinking.
Since I first registered and made a few posts, I have been through the end of a long term relationship, moved 1400 miles across the country, and still managed to work 70-80 hours per week.
When I do have some spare time, I am more likely to go fishing, go for a long walk, or turn to my first love: READING.
I just checked back in here less than a week ago after several months of not logging on at all-in between jobs for once.
So I would say that it is not that I have been offended, or put off by anyone, just a lack of time that I had available.
On a brighter note, I may be back to working in the industry again-gainfully employed as a gunsmith,but it is not yet certain.
