"Soft" bookings for the workshop

[GKFX]

Discuss this with Nat and Ellie first by all means, but last term for panto I had a spreadsheet where I kept track of who was in the workshop when and Nat seemed to be a fan. Features:

• Ability for multiple shows to be present at once (this is what I mean by the bookings being "soft")
• Ability for shows to make detailed notes on what they plan to do in the time - this makes it easier to work around others
• Some sort of disclaimer to the effect that booking the workshop isn't actually binding on anyone
• Marking out where shows are happening (based on Camdram) as unbookable time, and the ~30 mins before.
  This obviously isn't as essential as the booking of rehearsal spaces etc. but it's nice to know who's going to be present in the workshop
