Affiliate links are permitted only in the "Affiliate Programs" section of the forum, or in your signature.

Create ONE thread in the Affiliate Programs forum and provide detailed information about the program, and include two links: one affiliate link and one non-affiliate link. 

You MUST give others the choice to sign up through your link. Also, do not try to circumvent the Terms by posting about an affiliate program, and requesting others to "PM" you for additional information. Such conduct is no different than affiliate link spam.
