What about my topics such as "Favorite Jokers" or "Favorite Court Cards". Are they fine?
Those are fine, yeah.
I don't want the PCP turning into an advertisement board flooded by "check out this link!!" posts. If there is one overarching thread for a deck of cards, like the Monarchs, don't make a second thread asking "What do you think of the Monarchs?"
Use discretion and the handy search bar before making a thread you feel has been made before.
@John: You're fine, in the past few weeks there were people who would make duplicate threads every couple days.
