I would like to apologize for sending this for the hole list, but I did not find another way to get help! I subscribed to this list months ago. Now, I need to unsubscribe. I tryed the command unsubscribe to the listserver and got a strange messa- ge saying that I could not act in behalf of my address. I wonder: If I could subscribe, why can't I unsubscribe now? Does someone have any key for the exit door? Thank you, Fernando
