Release Dates is a calendar database that can be imported directly into MS Outlook and then synchronized with your Outlook compatible PDA (such as the Palm and Windows CE). This database contains the release dates for all known movies (both theatrical and home video), music, and PC software titles that are coming out over the next 3 months and beyond. The database is updated every other week to ensure that you have the most up-to-date list of releases. These updates are completely free for registered users. Registered users receive the newest updates via e-mail the same day they are released.
