I wanted to make a booking for the laser cutter for next Wednesday at 6:30pm but I’ve realized the Open Evening is at the same time. Can I still book it?
Also, I still don’t have shutter access - can I create the post of the booking without a host for now? (Assume there will be someone in at that time already!)
To answer the other part of your question…It would be a bad idea to create a calendar entry without a host specified, because members may assume access, only to find that the shutter is down.
