The Net Projects were projects in the late 90's created for use of the net community by an individual on a specific topic within the Dark Sun game setting. Topics range from The Deadlands, Armor, Weapons, different City-States, etc. Each NP had a set amount of time to run on the Dark Sun Mailing list, during that time the Owner of the Net Project send mail to the list requesting the type of info that was needed for inclusion into the Net Project and the format that the info needed to be sent in.
