On hiatus

Apologies to regular visitors. My PC has died on me (suspected motherboard problem), so I can't update from home. And I don't have time and I should not update during office hours. Besides all my photos and notes are on that PC, so I don't have much reference material. So, I am going on forced hiatus until I can sort something out. In the meantime keep on checking, maybe by then my PC would have been cured!
