I played World of Warcraft for over four years, and I had so many good days there! Anyone else remember the Bigredkitty baby Tauren raid for the Make A Wish foundation fundraiser? When we crashed the whole server by accident? https://www.engadget.com/2008/11/08/bigredkitty-an-open-apology-to-everybody/
Not every day was purely charitable, of course, but that was such a good memorable time. I never felt like I had such a good community of people before that day, like the power of the internet could be harnessed for good.
