my friend wants to start an authority site JV which will center about pushing theme forest themes (90% of the site) and wpengine affiliate program. Mainly theme reviews and seo targeting long tail keywords - the usual stuff. In the past i have only used themeforest on a small site and managed to rake in a few hundred bucks. as i see you only get the 30% from a new user's order. do you think it's worth investing money in a white hat site like that?
