If your assessment is correct and the magazine cannot be supported by the membership, the IJA should consider all options to obtain a magazine that is within the means of the members. The festival should not have to support the magazine. It may even be worth considering web publication. I don't know how the costs of maintaining a server to allow web publication compare with the costs of paper publication. I do know that generally computer costs have been going down over the last ten years, while printing costs have been going up.
Many professional journals are now available on the web in addition to the hard copy format.
Journals can be browsed via the web site and appropriate articles printed by qualified users. Journals and conference proceedings are also being published on CD rom in some cases. Personally, I think this idea is five or ten years ahead of its time. I don't think that at this time a high enough percentage of jugglers are computer literate to make this work. It will probably be necessary to solve the immediate money problems first.
