From AgentPaperCraft:

Test Night with Crafty is a weekly event dedicated to the forgers of Waypoint as convenient means of testing content for matchmaking consideration. It is also a great way to get constructive feedback on your map variants and game types. It will also provide you with a player base to help test your maps and game types through the community testing gamertag. Your content will also be observed by a secret member who reviews and suggests maps for matchmaking; this could mean thousands may eventually battle on your creations! Get more information in my thread in the Recruiting section of the forums.
