[DeTomaso] Help with posting on the POCA Forum

Dear Forum, I am keen to reply to Mr. Michael Shortt's posting in the Publications Forum of the POCA Forums. From what I think, I am supposed to be automatically subscribed to post and reply on the General Discussion sub forums. Alas, I am stymied. I to see that others have responded to his posting. Help? Warmest regards, Chuck Engles
