Intro

Hola! Amigos.. It been a while since I last release an Extension. I'm sorry I don't have an excuse.
Issue

I want a situation where as an admin, I can manage seller's activities (product: Author email to be specific) on my site, to some extent i can but, something is still lacking.. which was how to contact buyer regarding a particular product information. e.g. a book store (author's Email)

Well this extension resolved the issue listed above.
