Reporting from this end.
As soon as I logged back on to the TUG site, I got a textbox window telling me that my message had been read. After I clicked "okay" I then got another text box window telling me that I had a private message and asked if I wanted to read it in a new window. I clicked "Yes," but then was told that the message could not be read -- that the problem might be that it is being blocked by a popup blocker. (Probably true.) I could read the message by clicking the "Private Messages" link found on the upper right hand corner of the screen.
In short, it appears to be a no brainer.
