May be the same happened to you...
We haven't received the info-labview-digest since February. We sent several mails to Tom but never received an answer. We also tried to unsubscribe and to subscribe again. Unfortunately all this remained unsuccessful.
After that, a colleague tried to subscribe to the list from his private address. This was OK! He sent then a mail to Tom to mention the problem. Here Tom's answer:
*************
The problem is a firewall block between our site and yours. The
configuration of our firewalls is out of our control (we are a US Army site
and the firewalls are managed by higher headquarters).
*************
Until now our mail sent to the US army stayed without any answer (and will probably never receive one)...
So what can we do? We enjoyed the
info-labview so much :-((
