First let me state that I am a Member of the AMA. Why, it is the only game in town. I also use Bill Gates windows in my computer and for the same reason it is the only game in town that will work on my PC.
And now, about the AMA magazine. The AMA bylaws state that a report must be made to the members, it does not state how often to make this report or that the report has to be in the form of a magazine. The bylaws also state that the magazine can be put out monthly by order of the EC .

One poster wanted to know if the AMA helps with the cost of going to the Worlds. I can only say that when I when to help some friends that the AMA did not help. Now this was back in the 60s so I do not know if this has changed.
