• Upcoming ACCU Cambridge Meeting, 10 March 2025.
  6 March 2025

  ACCU Cambridge have scheduled our next meet-up - and it's only a few days away!

  https://www.meetup.com/accu-cambridge/events/306375573

  We have two talks lined up (although only one on the schedule at time of writing - as I m still getting that pinned down). So far we have ACCU regular, Chris Oldwood, talking about mobbing and pairing. There will be free pizza and drinks, too, thanks to Undo sponsoring the event.

  Hope to see many of you there!
