I have 2 ideas: authors personal affiliate system AND authors coupons system
Personal affiliate system - I mean not Envato affiliate system, I mean functionality which will give each envato-author ability to attract more visitors on his products pages using his own referral system. I want to suggest Envato create classic shop affiliate functionality for authors product pages (separately for each product page OR to author portfolio page) - its really can help make more sales because site-owners will have money flow and author will have a lot more purchasing - such business is good for all, everybody makes money.
Coupons - I mean classic coupons which author can create for his products and share them on coupon services for example, or on any another place by his logic. For example 50% Christmas coupons until 01.01.2017, or any another marketing events …
Of course in both variants remuneration pays by author from his own budget after Envato taken its fee …
I understand that this functionality is not simple and will take a lot of time - but why not to start to design it already today?!
