Another one of GAMA's employees has left the organization and rumor has it there has been at least one additional resignation.
The fact of the matter is that Dancey's actions were probably unethical and may be illegal as well. It also means that the current board is essentially without a mandate, since it appears that Dancey's intrusion of the board list was prior to the election and thus, there is the suspicion of this influencing the process. To salvage things, the board must hold another election.
It is highly unlikely that people will be thrilled to do business with someone who is suspected of a felony related to the industry, no matter how unwarranted or warranted it may be.
What does it mean to the average gamer? GAMA runs Origins and the GAMA Trade Show. These are influential conventions. Games are sold based on interest from hobby distributors, and if the opportunities to present products for a distribution slate is undermined, it means that you just won't get to hear about certain products. Your game store will not order them because they won't appear on catalogues. Independent distribution is difficult and is only viable for very large or small scale companies (the large ones have the book trade and name recognition and the small ones can do fine with direct sales alone).
In wider affairs, it means that there will probably be a review of everything Dancey has touched to determine whether any company doing business with him risks any sort of liability. Given how many things in the industry are determined by ad hoc, informal agreements (such as "gentlemen's agreement" surrounding the products that people like to talk about around here), this may have an effect -- ot it may not.
