We already have a library on WoP (:

That is a great idea, you should tell that your plotteam-leader as they are the ones who think about such scenarios for the sites! 

Is this still an issue? On the German site payment was not possible for about one day since the payment provider has been changed, but now it should work again.

World of Potter is a text based roleplay game, meaning that the game works by writing and reading texts.

Yes this is a bug, we are currently working on it (:
