That said, you probably ought not worry too much about what we think. We're just a bunch of retro computing nerds, after all. The most erudite, polite, and helpful bunch of such that you're likely to find around these here intarwebs, but still.
Like equill says, it's what you can contribute and learn and how you treat your comrades in arms that counts.
If you want some real feedback: I have noticed a couple of replies on tech questions that seemed a bit like wild guesses for the sake of making a post, rather than based on actual knowledge of the machine/problem at hand. Mildly annoying, but no reason to take a dislike to a chap.
