E-mail! We can’t imagine getting through our day without sending or receiving at least a dozen of them. Everything from gathering news to coordinating meetings, sending out notices and sharing documents happens via e-mail. So it’s important that your desktop e-mail client is a flexible, full-featured, powerful organization and management system. Thunderbird, from the creators of the Firefox browser, is one such program. We like it for its simple, logical interface, quick search ability, fairly powerful spam filters, ASS integration, message tagging, and downloadable plugins.
