If you ever wanted to read the first thing I ever wrote, Singularity 7, ( it's sold out basically now ) then you can now for free on Wowio. Same deal with the now impossible to find Blood Stained Sword, written by Dan Wickline that I drew.
Infact there should be a bunch of IDW titles over there now, with more being released in the weeks to come.
EDIT: yes, their website seems to be down until next month, due to them dealing with the new properties they'll be carrying. So just a little wait.
