Thanks for the input and I have now dug out some of the unresponded mail mentioned here. Turns out it was unread as well - I'll offer up no excuse other than what has been stated before. I've thought of the auto-responder, but given the attention to spam, think that unwise as it means my account is active and things would just bounce back and forth increasing an already unmanageable burden on my email volume.
As always, "that gary guy" has a pretty good idea.
wharvey, FewMiles and birdstrike (only found one email from you) - you'll have email within 24 hours.
Again, thanks for the input, it does help.
