Wow, real nice marketplace! Love it!
Though I do have a suggestion for improvement. Right now the marketplace users are person that know about DGC and want to support it. In the long run that will not be enough, so my suggestion would be to make it more "newbie" friendly by adding two info's on (on the top of the page (?) ).
1. What is digitalcoin (and why is it better than btc (?) )
2. How can I get Digital coin?
If you would add something like that, where A. the user could click on and get to the info page B. use this as headline with a brief description/info underneath.
Hope you like my Idea, let me know if you like it
