Okay okay okay okay . I know it's pretty much only me who is disorganised enough to want/need a Facebook invite but the best way to do it was this :
https://www.facebook.com/groups/679288942433337/?multi_permalinks=679289379099960&notif_id=1537262706220187&notif_t=feedback_reaction_generic
I created a FB group (above) for anybody else that feels inclined to track events that way. Couldn't do just an event without making it public (and I don't know everybody's real names so couldn't really gatekeep who was getting in/out of events). I made the group so that anybody that wanted to find it could but needed to ask request (I asked "where did you find this group" to kept gatekeep who was actually coming from this site) and then - once in - you could see the events.
At request, I've shut off all commenting beyond admin comments to ensure conversations stay on UKY and not FB and to keep the focus of that FB group to ONLY creating events for those that need the reminders (and it can make it easier to share photos).
Feel free to join if you're on FB and want to. If not, I won't be offended it's totally fine. If people further up north want to create a meetup and use that page to create an event, I'm happy to make whoever an admin so they can do that if they have issues just being a member.
