What are the best online tools for people who work at home?

Tweet

I work at home and there are some really cool, free online tools out there. I know I have some favorites -- so I'm wondering what other people's favorites are. Here are some of mine: Cinnamon Software's Talking Alarm Clock -- you download this and it will tell you when you need to get things done. Let a cute parrot, Albert Einstein or a robot remind you that a project needs finishing FreeConferenceCall.com -- many people need to have conference calls. This website offers them for free! OpenOffice.com -- Don't have Microsoft Office? Don't worry -- this Word Processing software is free -- and does so much more, even creates free PDF files for you! What about the rest of you...what are some of your favorites? :)
