Look thru the archive.  Marty posted an answer about this a long
time ago that explains the difference between log and alert and
how the database plugin is a strange purgatory-like beast.

Get oinkmaster.  It's a pearl script with a conf file that
allows you to update your ruleset via cron or whatever and have
signatures automagically commented out based on the signature ID
(SID).  If you're at all familiar with *nix and can read it
takes about 15 minutes to dl, unpack and use.

As for making your own rules and having them overwritten, just
create a new rules file and add it to snort.conf.  I use
"custom.rules", which never get updated cause the snort ruleset
doesn't (and prolly never will) have anything named that.
