The moderators do have a difficult job at times, and we must remember they are only human, and have lives of their own beyond watching the forum 24/7.
I have always been uncomfortable using the word "newby" it does seem to be belittling when all we are trying to say is "New caravanner"
Even though someone asks a "simple" question and hopes for a simple answer, for whatever the reason the answer may not be a simple as they hoped, and in terms of fault tracing, it often isn't simple.
But as Gafferbill points out there is a skill to imparting the right level of information to maximise the learning potential, but we are handicapped as we don't get to know the current level of understanding of most and especially new posters. So at what level do you set the response?
I too am guilty (possibly more than most) of diving into the technicalities. But also there are the occasions where the some advice given is definitely wrong or misleading and that needs to be corrected, and to show why, the reasoning behind it needs to be explained.
