Personal and small business information manager: Get organized, Backpack:
Backpack is one of many online productivity web sites. Backpack is my favourite because it offers its basic service for free. The service includes online to-do lists, an online whiteboard, wiki-like pages, and a reminder service that sends me reminders via email and text messaging to my cell. The free package is limited to ten active reminders at any one time, but I have never exceeded the maximum.
