Kind words thankyou.
I'm afraid that my old avatar picture is no longer on my computer. If the new avatar offends, I'll try to get another picture (possibly with a hat due to popular demand) in the next few days. Camera is on loan at the mo.
In the meantime, if we have to hear about you talking about the jump between 400/800 and 600/1,200 to your cats and fish in the street, whell, I'll look forward to it.
Also you may possibly want to look at
