We only have one person in our team that is busy cranking out manga for Project Pecan, which is Shinekomi.  She does a couple of Impromanga, which can be viewed at www.impromanga.org. Later, we will take your submissions to our site.

What is Impromanga? 

Impromanga is short for "improvisational manga".  Someone starts off the story, and it is up to other artists to elaborate and extend onto the story.
