I've been on hiatus for a long time and mostly only check in to make sure I don't lose my username lol.

But I've accumulated 20k "Forum Group Mention" events on my sidebar and just clicking the trash can makes them go away until I reload the page. I'm not too keen on the idea of individually deleting all 20k... is that what I'm going to have to do?

as far as i know, the fastest way to delete many events at once is to just click the trash can at the top of the event stack list; i'm not sure if you can see more at once on this page.

Depending on the forum groups you are in and (still) interested in their pings, you have the option to disable forum group pings. Just go to your ping groups, choose the group (click on it) and then click the "mute ping notifications" :)

I THINK (may be wrong) that a UA can clear your events via ticket if you cannot delete because there are so many. BUT, I think they delete all, not just a specific group.

I think I'll just put in a ticket. If there's any in there that I need to see, it's probably too late anyways haha. Thanks!
