Nooooooo....not the free excuse!
mysql or postgres are much better choice and they are free as well.

If you are comfortable with it and that's why you're using it, then so be it, don't use it just because you have a free copy of it lying around.

BTW, Apache is a great webserver...guess what...free too.

Just my $0.02, you can "cat /dev/null > $0.02" if you like...

perl -e 'print reverse qw/o b n a e s/;'
