Here is my proposal:
Every person who purchases anything on Second Life, reguardless of nationality or language fluency, MUST know how to find their transaction history. It must become a standard that all asset server errors are dealt with by giving the vendor your transaction history in a notecard. Just copy and paste and put your name on the notecard.
I know getting broken English IMs in capital letters is not the end of the world, but having to do a normally simple task for someone who does not make any sense to me and I make no sense to them sucks big donkey balls.
Are you with me people?!!! Teach all your newb friends how to get their transaction histories.
