Contact details and pedanticism…
Please note that until I return to the big smoke, my mobile will be very unreliable due to poor coverage, and other network issues up here. Feel free to contact me with it, but don’t be surprised if it fails. Email works, and so does my home landline.
Some people really do have way too much time on their hands:

Aside from amazement that anyone has the time to even learn that stuff, it all looks reasonably sound except for a couple of points:
1) Interpuncts — the point (no pun intended) in principle may be fine, but I don’t see any issue with using a decimal instead, as you are literally saying “17 and 99/100″ this can be correctly represented as 17.99 — preceding it with a £-sign gives it a unit. This allows the rules of SI units to be used with currency. Now what really irritates me is people putting the pound sign after the value. I just shot myself in the foot.
2) More fundamentally, these rules that are being discussed came from somewhere, and in most cases (as with most of the modern English dictionary) it was extracted from common use and formalised. If everyone makes these mistakes, maybe it’s the rules, not everyone, that’s wrong.
In general however, this is an impressively set together post.
