wpsc Support Tickets is an open source help desk and support ticket system for WordPress that allows you add support ticket capabilities to any WordPress site.
This isn't some port of another ticket system that's been hacked to run inside WordPress. This is a new plugin designed from the ground up specifically for WordPress.
