I'm going to add to this debate purely to put it back on top of the message board list, and because I like to talk and haven't done any recently.
This approach (whilst I've got your attention) reminds me of a book I read as a wee lad called "Grimble". The Grimble of the title was a young boy whose parents went on holiday to Brazil for a month without telling him; just leaving notes all over the house. One of these messages was written in green ink on a Garibaldi biscuit, and read: "Do not eat this biscuit as green ink is bad for you". I just thought I'd share that with you all.
