Affiliates
Want to be an affiliate?
What is an affiliate?:
A corporation may be referred to as an affiliate of another when it is related to it but not strictly controlled by it, as with a subsidiary relationship, or when it is desired to avoid the appearance of control. This is sometimes seen with companies that need to avoid restrictive laws (or negative public opinion) on foreign ownership.
It means your are associated with another site/group of people. You are not owned by them. You help advertise them, vice versa.
