Okay, version 0.1 of MTExitUrl will be relased soon. The functionality will be there, but the ability to track the exits will have to wait for a future version. If you have any comments on the software, you can email me at firstname.lastname@example.org
UPDATE 07/01/03: I have submitted this to http://mt-plugins.org/ and I am waiting to hear a response. Maybe they will see this page?
