From GNOME Project:
Tomboy is a desktop note-taking application for Windows. It helps you to organize the ideas and information you deal with every day. Tomboy supports many advanced editing features, but they won't bother you until you need them. You can choose one of the notes you've recently viewed from the menu or Search for older notes. The Table of Contents lists all your notes in the order they were last modified. It features highlighting text, inline spell checking, auto-linking web and email addresses, undo or redo, font styling and sizing, and bulleted lists.
