Author: jondaley

New Revision: 4116

Modified:
   plugins/branches/lifetype-1.1/tagcloud/plugintagcloud.class.php
Log:
capitalized words weren't being banned correctly. Everything is now case-insensitive. The first word also wasn't being banned, since 0 is similar to NULL and FALSE.  added nofollow to links, to keep search engines from indexing the search pages - it is better to index the page that actually contains the post in context.  Also changed a line-height -- stylistic change, the css should probably be moved to the config page.
