Chas, I suspect he's taking some "time off to cool off".
Letting people get to you in a forum is not a good idea, and letting them get you mad is an even worse one.
Then again, some people can dish it out ("it" meaning personal digs), yet can't seem to take it when it's returned in kind...they are usually the ones that take themselves too seriously.
Not saying Diki is like that, but, if the shoe fits...

I hope he comes back.
