Yeah, I will need to see how that one works as well. I do see WordPress does have it for version 2.62 I think the 2.5 is the version of the plugin.
Just a note on plugins. When I search for plugins, I normally don't even mess with the one's that aren't kept updated for a few reasons.
It is best practice to keep WordPress sites up-to-date as they are always improving it, and if you get too far behind in versions, updating can be a nightmare.
Although a plugin that has not been updated may work with your site and theme, again, down the road if you choose to change themes, it can also create havoc.
And as I have mentioned in other articles, don't update WP as soon as it's out...give it some time and let the bugs get worked out.
And most important, when updating, backup! and deactivate all plugins.
