X.commerce and eBay, Inc. want to protect X.commerce logos and branded marks, so they ask the community to follow the guidelines.
For this purpose, FPO X.commerce has developed a Press kit that contains various useful information.
For example, the X.commerce logo should appear in its original color and typeface. X.Commerce logos and marks should not be distorted, changed, or altered in any way. Also the logo should be placed on a solid, light colored or white background.
