I just finished my second WordPress plugin. here is some information about wp-postratings-my:

Shows users their WP-PostRatings and allows filters. You must have WP-PostRatings installed first.

See it in action at Audio Showcase (you must be registered, then use the “My Ratings” link).

and here is the wp-postratings-my WordPress plugins page, where you can download it. while I may provide updates here from time to time, all new versions will be posted there.
