Is there one already and I've not found it? I often come across events and think parents might like to know about it (and I'm just about to post one myself here on Chat as I'm not sure where else to put it) and I'm sure other people have events to share too.
An Events Topic would certainly make it easier for people to find event-based activities, but I'm not sure if creating a new topic is a lot of faff for Mumsnet. I don't want to give people extra work! :-)
