If you have one shred of care and concern for preserving and continuing the phenomenon that was Duckon,
From all indications that I have seen and gathered -- both from observers and people actively involved in your organizations, it is abundantly clear that your two organizations are fundamentally broken, and that a significant majority of those involved (or at least those who wield the political power) have no interest in fixing the root causes of the problems which are endangering not only the convention, but the corporation itself. Some of these problems have existed since before I got involved with DucKon about 10 years ago, so they can't be blamed on any one specific person or interpersonal conflict; they are endemic and systemic problems with the way your organizations are defined, executed, and allowed to be held hostage to personal ego.
As I recall, Super-Con-Duck-Tivity and DucKon were formed to foster and encourage children's science fiction literature. At that point, personal egoboo, self-vindication, and preservation of personal pride -- while present -- didn't seem to be playing a significant role in the operation of either entity.
All indications now, however, point to both organizations being much more concerned with those issues than with serving the interests and needs not only of emerging writers of children's SF, but the general Chicago-area SF convention-going public-at-large.
Thanks to the actions of key members of your convention committee and board of directors in the past year and a half -- and particularly in the past week or so -- the perception of DucKon and Super-Con-Duck-Tivity has been seriously damaged... perhaps irreparably. I won't address my (granted, incompletely informed) opinion of whether those actions were right or wrong; the fact remains that highly visible members of both organizations have acted and continue to act unprofessionally in public and/or semi-public arenas, and the result is that a deepening negative impact is spreading throughout many fannish populations which have traditionally been the mainstay of support and creativity for the convention. Doing things the way you have always done them is only alienating the people you need most to continue operating the corporation and the convention.
Stop. No, really, I mean STOP. Frankly, I think the only way you're going to be able to salvage the situation is to take a step back and, if you can do so without serious financial or legal repercussions, skip holding DucKon for a year, or even two. Use the time to redefine yourselves, both as a convention and as a corporation. The status quo is no longer sufficient, and indeed, has become destructive.
