I hope Guest checks in again, too.
Guests don't know how to trace threads, (and some oldtimers forget to set up a trace). They come back 1 or 2 days later and the thread has vanished off the list, sadly often because some *(#&$ has started 50 dumb BS threads.
(I'm guilty of this same forget-to-trace problem. I've had 2 threads disappear on me, and when I searched the Forum for the keywords in the title, nada. whaddyagonnado.)
