I am very sorry for having been away so long, but on the 19th July I was sectioned again and I am now in the Chichester Mental Hospital. Only this afternoon have I obtained a dongle, so I can access the web from inside the hospital. I am afraid I haven't got time tonight to review the discussion (I meant to turn in the computer at 8pm, and it's gone 8 already), so I'm just posting here to say I haven't died! I hope I will have time tomorrow to get back into the discussion (if you'll have me!).
