OK folks, after some head scratching this afternoon, we're back.
The problem was space. We had plenty allocated, but the server itself ran out. Seems an account on the server we share had about 7 Gigs of unread email on it - no doubt most of it SPAM. Leonard contacted the sysadmins to the system, and they found the problem quickly and corrected it.
There are some missing threads. These threads were lost during the time the server was running out of space. I have tried to recover these, but to no avail. When these threads were being edited and rewritten they were truncated beyond beyond recovery.
If you posted and found your thread missing, it was not deleted because of angst or anger, just a server that was flat out of space. Please repost if you have the time.
My thanks to those who emailed Leonard and myself quickly once problems cropped up. My apologies for the lost posts.
Regards - Bob Kruger
