rpm -Uvh and your settings are safe john
Thanks, John. That did the trick, and, as you can see below, I now have a sig file. All settings preserved, mail not lost, etc...
One thing, however, this seems to be a nightly build. It's version number is 20041216. It seems to work just fine. Down the road, should I switch to a stable regular release, and if so, how, the same way?
To the replier who pointed out that the suggestions on where to look were wrong - he was right, however, in 'tools/account settings' on the default tab, there was no box at the bottom to specify a sig file - I looked many times, and now that I have the setting, I'm doubly sure it wasn't there, because it's blatantly, stare-you-in-the-face obvious, now. It would appear that the version of Thunderbird that was released with FC3 was missing this feature, or it may have been stripped by the upgrade process 'yum upgrade' that I ran after installation. Anyhow, all is well now.
