personal knowbase
The folks over at Bitsmith Software were nice enough to include HelpSpot in their list of small business resources, *[This image was lost to time in my blog transition]* so I figured the least I could do is post a link to their Personal Knowbase software. Personal Knowbase is basically a knowledge base for yourself. Keep track of notes, messages, files, etc all searchable. I haven't used it (it's Windows only) but it does look interesting.
Thanks Bitsmith!
