Very true Guest Homey, you didn't, but you see our Ron ain't too great on either comprehension or attribution.

Now from what I have read of your posts you have restricted your input, very much like Amos in another similarly long thread, to quoting articles by others. A fact that has seemingly escaped our Ron's notice.

I most certainly do not see the need, requirement or benefit in even attempting to "impress" Ron Davies, who would in all probability have to get somebody to explain it all to him in the first place.
