Paul,
It seems that he has *some* experince but the absense of a CV is a negative point. I have no problem with nicknames as long as I know the identity behind the handle. Going through recent posts I think his name is George Cook but, being UK based, the name means diddly squat.
I am uneasy about the way he throws criticism/advice around like an armchair general (and there are far too many of them around) and is far too liberal in naming names.
All this is my own thoughts and posted under my own name & email address - if I don't feel I can post under my own name I don't post it.
