However, I cannot post messages;
I get an error message that there is a problem with the mail queue.
(This could be due to the fact that my UID has changed,

When moving from F-15 to F-16 or back,
I have to start as root, and run "chown -R tim.tim /home/tim",
after which I can logout as root, and login as myself.)
Yes, that's because of the UID change. You can run the following (as
root) while running F15 to change your F15 UID/GID to the F16 values
and you won't have this problem:
groupmod -g1000 tim
usermod -u1000 -g1000 tim
chown -R tim.tim /home/tim
This assumes that your UID and GID on the F16 system is 1000 (and that
1000 isn't taken on the F15 system, which is unlikely). Make sure to
run "echo $UID" or check /etc/passwd on your F16 system to ensure that
is the case. Note that changing the UID/GID on the F16 system to
match the F15 value is inadvisable because system daemons most likely
have already been assigned UIDs between 500-1000.
