Hi, Liz: Go to https://www.pacesconnection.com/groups and click on All Groups. See if there's one close to you!
I'll ask the support folks who run our platform if we can have an alert just for webinar events. That's a great idea.
In the meantime, I suggest stop getting alerts for all calendar events, and making a note to yourself to check the calendar every couple weeks, and choosing to receive alerts from the ones that you want to be reminded of.
Cheers, Jane
