When signing up for the playtest, you sign an agreement that basically says you can’t quote or share material from the playtest packet.
However, recently, Wizards of the Coast has started to sell modules and the Ghost of Dragonspear castle book, which comes with a rule set for DnDNext. When purchasing this module, it does not ask you to click to agree to any playtest rules, or similar thing.
Additionally, officially the “public playtest has been completed.”
Does this mean that I can quote rules from the rules which comes with the modules, or are am I still bound by the agreement for the public playtest?
