Interesting - can you specify more details about:

• Site functionality - this sounds like a user-based system - if I sign up as a user of this marketplace, what exactly can (and can't) I do with it, in detail?
• Competitive advantage - what makes you / the team well-suited to pursue this project, and what elements does this marketplace incorporate that will attract users to it over alternatives (and which are the alternatives)?
• Marketing plans - how do you plan to inform users about this marketplace, and what do you expect your userbase makeup to look like, roughly?
• Does this marketplace use Wyvern? Ethereum? Both / something else? What currency will profits be taken in, and how will they be converted to Ethereum for dividends?
• Shareholder governance mechanisms - how will shareholder preferences be taken into account? Will you be using something like Aragon?
• Development resources - who will be developing this site? The dev listed in your announcement? Is there a team?
