I have to send regrets for tomorrow, very sorry. My family is moving in and
we have to do quite a lot of set-up work as you may be able to guess ;)

I'll catch up on the minutes; for the record - all my actions continue,
though I'm confident I can complete most of them till next week.

Cheers,
      Michael
