I was thinking the same at the eginning of the week and was about to contact Neil but looked at his profile and he had been active the day before so he still seems to be looking in. Just choosing not to post.
I can report that Dave’s pendulum is still swinging. He emailed me back and in his words “I’m fit for nothing, concentration is shot” Seems he is an awkward sod too as it is proving hard to find what is wrong but he is off for more tests next week.
