Thunderbird to Get Calendar Add-in

It looks as if Mozilla developers are attempting to make their Thunderbird e-mail client more competitive with Microsoft's Outlook. A roadmap to integrate a calendar application with Thunderbird was posted recently, which details the project known as "Lightning."

The group hopes to have basic functionality ready for release in November. Better Thunderbird integration, e-mail and task linkage, as well as CalDAV support are goals of the second revision, for which no timetable was given. Successive releases of Lightning will add localization support, device synchronization and cached offline calendar support.
