It looks like the forums were cracked this weekend and all topics in this forum deleted.
We will be switching to new forum software as soon as possible. We will try to restore the messages in this forum before the switch, but that may require dropping all recent posts.
Sigh.
It is regretible that there are those on the internet that revel in such mahem. Be glad it was just a wipe-out. Another site I frequent has closed for an unspecified time because a virus has somehow become attached to their coding and anyone using the system has become infected. Worse that would happen if you're successful is the deletion of duplicate topics.
