My thanks to Helen for explaining, better than I was able to, how things work round here.  My apologies also to Laika; unfortunately, a lot of people do tend to treat us as an information bureau, which gets a bit annoying sometimes; hence my reaction.  I certainly meant no offence, and I do hope that you will feel able to visit here whenever you want information that we might be able to help with.  Generally, we'll post that information to the discussion thread rather than send it by email; that way, it's available to everyone who might be interested.

With best wishes

Malcolm
