The board publishes lists of owner interested of selling shares (weeks) as well as people who have shown an interest in buying shares (weeks)
The Board verifies that a person wanting to sell shares actually owns the prior to publishing a listing.
Other than that the board accepts no responsibility for the selling and buying of shares. Nor does the board actively match buyer and seller listings. It's of to all interested partys to actively monitor the listings themselves.
Questions can be answered by Peter Asztalos, responsible for sales related question on the board.
