I know that people have asked me about that, but, my readership is truly global in scope. To print a magazine, I'd have to work about three or four months out... then, I'd have to pay for postage in a bulk rate for global distribution, which would have all manner of political and economic red-tape, then, my expenses would sky-rocket.
Right now, the magazine is FREE and will remain so, but, the cost is largely absorbed by the rest of my publishing activities.
Online distribution is the only practical way to reach our 100,000 readers (world-wide). Hence, I can continue to offer the magazine for free and every ukulele player out there can read it online, or print it and read it offline if they so desire. I have made it high-resolution enough so that it prints pretty well.
The effort is worth it. If I tried to offer it in print, I'd have to be a wealthy man with no thought of the cost and plan each issue much farther in advance.
