Thank heavens for small mercies. So long as someone understands what the point is, its all A-OK!
On a slightly related note, I was at Rempstone yesterday and only made 3p. Either someone else is collecting the offerings tax, the Dorset locals are getting poorer or they've finally realised wedging 20p pieces in cracks in standing stones just isn't on. Not sure what it is, but I'm loving it.
