Just notice that
(if things didn't change in the mean time) the cards will be drawn "face down" so you need to click on them to "play them", making them visible to others. Also, there is no "hand", meaning that the cards will be associated with the post they are drawn in. Sometimes, this makes it difficult to find them again so you may need to take that into account.
Oh, interesting. Does the forum software keep track of which cards have been drawn between posts, though? (E.g., if a King of Hearts comes up in Post 1, it won't come up again if someone draws cards in Post 2)?
