Adding words to a banned word list
When you enter a word, set the Pattern-type to wildcards or regular expressions.
Wildcard uses an asterisk (β*β) to match any number of any character. For example, re* will match all words starting with βreβ.
Regular expression uses Perl regular expression syntax. See
http://perldoc.perl.org/perlretut.html for detailed information about using Perl regular expressions.
