A basic plugin that *excludes* posts from one or more categories from appearing on the front page.
April 11, 2007: Based on the MySQL documentation page MySQL 4.0 and earlier does not support subqueries. Version 1.0.2 was rewritten to use a SQL JOIN and a DISTINCT clause to exclude the catergories instead of using subqueries. Thank you to Jason York for stumbling on this little gem and for providing the workaround.
1.1.1 - Fixed a bug where new posts, after you have upgraded your database schema do not get filter appropriately.
1.1.0 - Updated the join and where filters to take advantage of the schema changes in WordPress 2.3
1.0.3 - Got rid of the extra carriage returns at the end of the file. They were apparently causing "Cannot modify header information - headers already sent" errors.
1.0.2 - With Jason York's help, we re-wrote the plugin to use SQL JOIN and a DISTINCT clause so that the Plugin is both compatible with MySQL 4.0 and does not create duplicates.
1.0.1 - Updated the readme.txt file to address a MySQL 4.0 incompatibility. No code change at this time.
1.0 - Initial Release.
