I'm part of a hobby/ special interest group. There's about 15 of us and we meet regularly. Due to the nature of the meet up, there's a rota required for hosting, leading and food. Because food is involved we also say whether we are attending or not so they can be catered for approximately.
To enable this to run smoothly we have a shared Google calendar. There's a pro-forma element with the rota bits and then we all enter whether we're attending or not. For over a year it's worked really well. Around 6 months ago a new person joined the group. Lovely person who brings a lot to the group. But oh my, they are absolutely incapable of using the diary. I have personally given them many lessons on the use of the diary. They also use Google calendar as their main diary/ calendar (which is where the problem comes from).
So over this time we've had multiple entries deleted (repeatedly, i.e when we've replaced deleted ones they've been deleted again and again, despite asking not to) all group diary entries start with DO NOT DELETE). Then they add other entries in to the diary, things like car in the garage, hospital appointment, MOT due, lunch with Sarah etc.
Every single entry then populates to everyone else who has the shared diary. I've explained to them that it's doing this, how to stop it. I've shown them multiple times and I've given them a screenshot by screenshot notated guide. Others in the group have also done this. Yet after 6 months they've still not got it. I don't think I'd be so annoyed if they didn't use Google calendar as their normal calendar!
So aibu to just delete the none group related entries? They're taking over my (and everyone elses) calendar. Several group members have shared their frustration with me.
