Ya, you're right about more credit for people who are rookies with that kind of projects. Tho, the major fact is that most of them dont read the instructions and just click everything everywhere without trying to undestand... gniiiii, that Windows (tm)(c) culture makes me becoming mad !
Perhaps some people should work on a better documentation (easy to say, of course, more hard to do, or to get involved in) and provide more clear technical details for the less experimented users...
