Is there a way to find out how you got a gold account? I seem to have a month's worth of one, that started last week but I don't know how or why. I did have someone randomly send me a gift box recently, so I guess it could have been that, but I do not know for sure.

Someone might have gifted you a buddy gold account, though not sure if it would say who in a event message or not. :(

I feel that my gold account has been extended. Maybe someone sent me a gift ,but I didn't receive the message too.
