Jack,
That looks OK for a "windscreen ID", so forum members can spot each other. Now to make this simple to produce, how about having a self print facility on here. Have a blank that we can type in and then print off, on to vinyl sticker sheet, or cards, to suit everybodies different wishes, ie m/cycles and A vehicles don't usually have windscreens.
The large letters HMVF be dropped and changed to the website address, with the full name of forum below as you have done already.
