I'd like to add some constructive criticism and maybe some assistance in the right direction.  I think Darkcoin could use a new site, a new wallet splash page, and some additional marketing material but before everyone goes off doing their own thing in order to claim bounties I think the Darkcoin brand needs to be setup.  Darkcoin needs an official logo.  Along with this a branding guide.  Color schemes need to be set in stone. An official font needs to be chosen, a font size, font weight, etc.  There needs to be a model from which all additional marketing materials are created from.   Without this in place you do not have a brand.  The coin will be stuck in the same place it's in right now as far as marketing goes.

By no means am I trying to say that any work done so far is not quality work.  I'm only suggesting that brand guidelines be set so that everyone's work focuses on advancing the Darkcoin name. 

Think about Coca-Cola, Dr. Pepper, Pizza Hut, the Bitcoin 'B' icon, etc...  Every recognizable company has a set branding guideline.
