I am a subscriber. Unlike most magazines that start out as a newspaper-like black and white, and slowly work up to a color magazine, this one took off in full glossy color right from the start. The staff is attending various reenactments, etc. at forts and events to promote the magazine.
The articles are very high quality, annoted with footnote sources, well illustrated. My only concern is that most all the articles are currently written by their staff and they will need to ramp up their contributing writers over time so they don't burn out. But the magazine is growing subscribers fast and I think they will do fine.
If you are into reenacting or good historic information you can't go wrong with a subscription. If you subscribe you can get the back issues and have the full set(I think they are issuing their 5th magazine right now?)
