I contacted the publisher a while back asking about the expected release date for the 5th issue.
Michelle Weidman was kind enough to get back to me on December 15th and let me know that they are still working out production kinks. She stated that issue #5 was getting close to completion and that they hoped to have it out shortly after Christmas.
Thanks for letting me know this information. I'm hoping it will be arriving this week, because Christmas has slipped on by and January is over halfway gone.
I think it is important to state that I am a supporter of the magazine effort and have twice subscribed for a full year (issues 1-4, and 5-8).
Let's hope things will speed up during 2015.
