Dare I Ask? Why No "Seller Central - Professional Selling" Category

We have a Buyer Central Professional Buying but no Seller Central Professional Selling. Are not Sellers professional also?|||All sellers get paid for selling. Therefore they are "professional" by default. This board was originally created for people who buy for business or resale.|||Not sure why it would be needed, sellers have so many boards already. Besides really obvious ones like Seller Central, Auction Listings, Checout, sellers basically control Feedback, Trust and Safety and many others.|||And this board is really for all buyers, not just "professionl ones". Most regulars here, with some notable exceptions, are also sellers.|||
