I just realised that I haven't been receiving messages to the Manchester list since November, so I didn't see the messages from Anna and David until today - sorry!
I switched to a new groupware server recently and changed all my mail accounts and sieve filter scripts, somewhere along the way I stopped getting the Manchester@ messages, although I'm still the list admin.
Anyway, should now be fixed, but just wanted to explain and apologise.
Best,
Sam.
