OK, I'll admit that I had never heard of this (US) e-publication before. Evidently they had a booth at Historicon in July, but I spent so little time in the dealer's area I missed it. A chance FB post over the weekend about the 25% off subscription dale they were having lead to a subscription (and a free back issue when I mentioned publicizing it on my blog. The sale is good until October 11th.
MMM for short, is a digital only product; there is no print edition. The "production" quality is outstanding; professional, and fully equal to the British glossies. The sample issue was 94 pages long, and packed full of an all wargames relevant mix of historical background, games played out, product reviews, rules reviews, book reviews, and more. Despite the title, this is NOT a magazine for collectors (although there are articles on modeling and painting) It has been a long tome now since the US had a decent wargames periodical, even if this isn't quit ion the style of the long defunct Courier or Midwest Wargames Newsletter. The 25% discount (with the FALL coupon code) brings the cost to about $3.50 an issue for 6 issues; well worth supporting, don't you think? I did! I like it enough to consider contributing in the future, at least to the reviews section.

PS - I had a bit of trouble getting the coupon to work for me on the website, so emailed them via the contact information and it was all sorted out very quickly.
