Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
I would also like to see a forum built into the platform. Wealthy Affiliate has a unique way of building a community and I understand why they shy away from a standard forum type of format. Instead, they want to promote live chat sessions, blog posts, private messaging, and public questions where people can comment below. This type of setup is pretty cool at times, but I also do enjoy forums where I can just browse by topic.
