Example of an Slrn scorefile

% A percentage sign indicates that what follows is a comment.

[*] % This rule applies to all newsgroups
Score: -100 % The article's score is reduced by 100...
Subject: Make Money Fast % ...if the subject header contains this phrase

[news.admin.net-abuse-sightings] % This rule applies only in the specified newsgroup
Score: 200 % The article's score is increased by 200...
From: user@example\.com % ...if the From header contains this expression

The two rules would be combined to increase the score by 100 if both were triggered by the same posting.
