One of my weaknesses is that if someone asks me a question I feel obliged to answer it, or at least write a polite personal reply apologising for not giving an answer. This takes time and as my time is limited this means I have less time to provide answers, and update the web site for everyone else.
Most of the problem emails appear to come from people who want to ask a question irrespective of whether it is relevant to the way the web site is run, and/or are too lazy to include relevant information. For years the "Ask Chris" page has included guidelines and examples of what I am looking for - to the point that it probably puts some genuine people off. I have decided to try a different approach.
The "Ask Chris" page starts with a comparatively brief introduction, followed by the paragraph:
Rather than urge you to read the Frequently Asked Questions (which many of you will not do) I give below the text of the standard letter you will get if you don't read them and ask an "out-of-court" question.
The letter (below the fold) lists the possible reasons why their request might be rejected, and all I need to do is to send the questioner a copy of a letter they have already seen (with relevant paragraphs highlighted).
