We have 8 issues under our belt, nailing out one a month (kind of like a comic!) - we're on iTunes and a few other places!
Rather than link individual issues, we have one page with links to all the issues! You can check it out here!

If you enjoy it, please help spread the word (Facebook, Twitter, etc). Word of mouth is the best advertising, because it comes from a trusted source (to friends and family!)
