Here is an update to my original posting. There are rumours (from reliable sources) going round that about 20 COs have been "reassigned". I should have mentioned that I'm in the UK. I wonder if the GB member visiting here has anything to do with it.
Just to clarify when I said our co was a pretty good sort I meant that he takes an interest in people, gives lively talks and doesn't have weird food requirements. He is still a company man through and through and has been used a lot by the society. Him and his wife are now looking for somewhere to live - I think they have had offers of temporary lodgings.
