I see your point Si, but most people aren't interested in their gas boiler, and have no interest in learning how it works/participating in its up-keep. I'm sure if this was GasBoilers.net they might be.
I'm no mechanic, and I know very little about exactly how a car pieces together. However I am fairly handy with a spanner (after spending several years as a technician). This means I do tend to ask a lot of (seemingly) stupid questions as I like to be sure exactly how or why I should be doing something on the car, having not done most of the jobs I'm attempting in the past, but I do them so I can learn.
The OP could have gone out and bought a massive bar and jumped on it till the bolt came out, but for all he knows that could have broken it (not everyone knows the bolt is supposed to be 175nm tight), so he asked the question. If everytime someone asks a question they get scolded for it, next time they're less likely to ask, which doesn't necessarily mean they're less likely to attempt the job anyway and c*ck it up.
This isn't a dig at you personally by the way, you know that I appreciate your input on here, and I've benefited a lot from it over the years

. However there does seem to be more and more posts from lots of members dismissing people trying to 'have a go' because they don't already the know the answer to the question they asked, isn't that the whole point in having these sections?
