I hope you have fun in the guild, don't be shy to chat and ask about things, or indeed share experiences and knowledge. We have at least two other Dutchies in the guild, Megashira and er, Kaswe... somebody else. I live in Nijmegen though I am not Dutch.
You'll pick up the jargon and all the acronyms quickly, and I wouldn't worry too much as an awful lot of them are "if you don't know what they mean, you don't need to" type of words. And as always if need be, ask in the Guild chat.
I hope you have some happy hunting with us.
