Being a Dream Team member, gave me the opportunity to review this RefCardz, before it was published. This is the first thing I did, after becoming Dream Team member, and I enjoyed every bit of it.
Lets take this opportunity to thank our beloved Geertjan and Patrick for all their hard work, they had put in for this, was fruitful!
