If you're going to apply for a position in which you're going to contribute content to OC (maps, models, textures, code etc.) make sure you'll have access to a printer and scanner.
Since Valve needs every content contributor to sign an agreement, your work would be useless to us if you're unable to print and scan the agreement.
Should you leave the team for whatever reason you may have, all content you created for the mod untill then will stay with us.
It will still be your work and you can do whatever you want with it, but we'll have your permission to use and redistribute your contributed content in OC, as well as modify it if necessary (to fix bugs, bring it up to par etc.).
You automatically agree to this should your application be accepted.
