As a new user still fumbling around in game, I'm not sure if I accidentally cleared the 'event' tab for this notification, but I noticed I randomly got the Gold Account for a month. Spent the last 20-30 minutes trying to find the person to thank for this delightful gift :') Instead, I guess I will pay it forward once I've spent sufficient time on this site!

(If you were the person who gifted me the GA, I'd still like to know who you are so I can thank you personally!)
