think most people found better places to discuss Gulden than in this snakepit of butthurt people
What are you butthurt from johnnybraveau? Did you go in an dark alley with Rijk
Ok i admit that joke was too easy too make 
I saw some good discussions with Rijk in that other Slack channel where Rijk showed his best side again.
I saw this article in German language but do not know if it is interesting or not?
