Welcome aboard, Mark! To add more cream to the "Keeton" joke is that Keeton is actually quite quiet on the forums due to work pressures. He and his Mrs pop their collective heads in once in a while to find we're using his name in vain and referring to him as 'The Glorious Benefactor'. Great to have you on board.
I'm tentatively bowing out of this one - I really, really need to finish Icar Version 4.
