This is a simple plugin that enables users to modify the order in which posts are displayed on all pages(or in selected categories) of the blog. This is very useful when 
you have a blog in which you want to display posts in the order they were posted, from the first post being the oldest one, to the last post which 
is the most recent one, or the other way around. The options provided with the plugin at this moment allow users to order the displayed posts by post date, post title, 
post author, last time modified and post slug, either ascending or descending.
These post display options can be set by accessing the “Manage->Custom Post Order” link, for wp2.6, and “Tools->Custom Post Order” link, for wp2.7.
