While the FAQ maintainers don't offer a 'help' service, they're very keen that you understand the answers they've already written. They're (almost) written "in a vacuum", to provide something to cover a set of questions that have arisen; it's always possible that they're written in a way that a novice won't understand them.
Which is where you can help the community. Mail the maintainers (uktug-faq@tex.ac.uk) to report the answer that you find unclear. Time permitting (the maintainers are all busy people), we'll try and clarify the answer: so, with a bit of luck, we can together improve the value of this resource to the whole community.
(We need hardly say that we look forward to hearing from none of you: but we're not so arrogant as to be confident that we won't!)
