Here is a copy of the logo guidelines I heard about at the latest Captains Meeting in case anyone needs it:
We cannot sell anything with the American Cancer Society or Relay For Life logo on it. (Tip: you can give items as a gift in exchange for a donation). Our Second Life (RFL) theme logo may be used on items that are sold in RFL Vendors.
When using the American Cancer Society or Relay For Life logo, do not change or alter it in any way.
Gambling and Games of Chance are not allowed. (Example: Greedy). You may place a Relay For Life Donation Kiosk near a Greedy table or other games and encourage people to donate some or all of their winnings.
