Only needed if we've talked to you about including your work
We would like to include some of your awesome modifications you guys make to NS2, to make them official changes to the game.
However, to cover our butts, we need to make sure that we own all the rights to everything in the game (maps, code, artwork, sound, etc.). If we don't own these rights, we are potentially liable for copyright infringement.
So if we decide to include some of your changes into the game directly, we need you to assign your copyright to your work to us directly before we do that. To do so, you need to complete the contract attached and send it to me. You only need to fill out one of these forms (there are three different formats, all identical) and then you can e-mail it to me at firstname.lastname@example.org or fax it to me at (415) 651-9789. Make sure you include your name, physical address and your forum handle or community nickname so we can keep track of who has submitted them.
