I wish people would take a little more time in their answers to specific questions. Just pointing everyone to KB articles is equivalent to one tick above zero effort. I can search and find KB articles, read them and as long as they are well written understand them. But if that were the case, there would be no need for these BB sites would there? If one takes the time to answer these queries, the least they can do is to summarize the articles, otherwise all your help is merely rudimentary skills, and I cannot see how people would give a thumbs up to these replies, unless of course the learner is too lazy to look this up themselves.
