This page lists the architects of the dream worlds, so to speak, and a brief description, as well as information on which maps they have made and relevant contact information.
Authors are categorized as such: core and associate. The former are the main Japanese team members, who can contribute to the game directly, following reservation and runner declaration protocols. On the other hand, the latter are authors foreign to Japan, subject to proxy implementation protocols.
The Six-Month Rule is an agreement between the authors, that if an author fails to update within six months of their previous update, then their maps may be freely edited by other authors (unless otherwise specified). The rule is reset when they update again. It's a pretty good litmus in determining whether an author is active.
To see when an author was last active, please check the Version History or check the changelog.txt file included in the main folder of the game.
If you are interested in contributing to the game's development, please take time to read the Content Contribution Guidelines.
