My theory? Everyone!
The ROBLOX Team would like to thank all the users who have poked their avatar’s head into the ROBLOX test site (test.roblox.com) on occasion to help us in our relentless pursuit of nasty bugs and other glitches. There has been a legion of helpful users, and it’s impossible to thank everyone individually – so we’ve got a little something for the whole community.
As a small “Thank You”, for a limited time only ROBLOX is giving away some free heads!
