If you have Dunstan's Time Since installed, this plugin uses it for the title="" attributes on the comments and posts. (For WordPress 1.5) Author: Brian Meidell Author URI: http://meidell.dk/ Version 1.5: Now works without LOCK TABLE and CREATE TEMPORARY TABLE priviledges. Version 1.5.1: Can't remember what I did here Version 1.5.2: Fixed count select statement to not include spammy comments Version 1.5.3: Properly excludes track- and pingbacks Version 1.5.4: Excludes posts that are not published, even if they have comments Version 1.5.5: Fade old comments, fixed bug that wreaked havoc with Time Since Version 1.5.6: Bugfix from Jonas Rabbe (http://www.jonas.rabbe.com/) pertaining to timesince Version 1.5.7: Bugfix so old colors can be darker than new colors (stupid oversight), thanks to http://spiri.dk for spotting it. Bugfix where single digit hex would cause invalid colors, thanks to http://www.wereldkeuken.be/ for the fix. Version 1.5.8: Updated to work with WordPress 2.1 alpha by M.
