When I tried to buy shares yesterday (5/30/07) on Scottrade, a message came up saying buys are not allowed on this security please call your local branch office to place the order. So I did, and they did let me buy PAVC shares, I asked him why they were doing this. He said to make sure that there is no "foul" play on this security. Just thought I would share the info. Thanks for all your great DD
