I was out of the website for a couple years and on the meantime I've accumulated almost 10k of forum group mentions. I'd really like not to delete all of these by hand, and clicking the trashcan only "deletes" them until I move to a new page. Can somebody help me?

Just keep trying to delete them using the trash can, it usually takes me about 3 pages of having to click it but it eventually goes through :) Other than that, I don't think there's any other way. Good luck!!

- you might be able to get staff to delete them for you, if you file a ticket :)
