From the makers of the well-known Firefox web browser and the Thunderbird mail client comes Sunbird. Mozilla Sunbird is an open-source, cross-platform calendaring program with similar functionality to the one found in MS Outlook. Sunbird is available as both a stand-alone version and as a plug-in to both Firefox and Thunderbird, which is simply called 'Calendar'. The initial public release, version 0.2, is a very early beta and is not without issues. Although Mozilla.org is known for its high quality software, they definately need your help to iron out the bugs. Do your part and download a copy today!
