ComiXology has launched a new portal, comiXology Submit, through which independent comic creators can upload their comics and graphic novels at no cost.  After approval, comiXology will prepare submitted work using its Guided View technology and then make it available on all the comiXology platforms, including iPad, iPhone, Android, Kindle Fire, Wndows 8, and Web.  Creators and comiXology will split the profits from sales of their work, with creators retaining full ownership. 
Submit will be used both by up-and-coming talent as well as better known creators who want to offer works no longer in print. 
--Disclosure: ICv2 has a business relationship with comiXology as a representative for its Retailer Tools; ICv2 CEO Milton Griepp also serves on the board of comiXology.
