The community-uk list is incredibly low traffic, so it makes perfect
sense to move it to Mozilla’s Discourse instance. 
Discourse is great in that it can be used like a traditional forum or,
if you prefer using mailing lists, it can be used like them too.  You
can start a topic on Discourse itself, or by emailing
firstname.lastname@example.org after you’ve signed up.
As an example, @yousef has just started a thread to organise Air Mozilla
training in the London MozSpace over the next week. 
Cheers all, and see you on Discourse!
