I have posted a page for the next Cambridge meetup:
http://meta.wikimedia.org/wiki/Meetup/Cambridge/11
It is on meta by request (more sisterly). The page at http://en.wikipedia.org/wiki/Wikipedia:Meetup/Cambridge_11 also exists but the intention is for people to sign up on the other page. Apparently the Cockneys don't get confused by this, and I shall attempt to check the meta page frequently.
