The new Nihongo website has much more content to be added in the very near future, but the main code has been finished. The code for adding a comments feature has been written and tested successfully, and will soon appear on the later comics (possibly all of them) and immediately on any comics released after 10.
The extras (such as "Guest comics") are for the most part not on the site, simply becuase I wasn't sure how they would best fit in my new system of organization.
Anyway, visit here to see the new Nihongo Comics website Aikeru has coded from the ground up so we don't have to use someone else's system anymore. =)
