JottIt : Online NotePad Replacement
JottIt offers a wiki-like (but way simpler) service to create, store and edit notes online. You can think of it as a web-based notepad application that can be easily edited by several people (given they were invited befrehand).

Feature Overview
- Create, store and edit notes online
- List all of your pages under custom URL (i.e. makeuseof.jottit.com).
- Make pages private (req. password to view and edit), public (req. password to edit), or open (can be viewed and edited by anyone).
- Invite others to view and/or edit pages.
- HTML-enabled: Add links, format fonts (bold, italic, etc.), create tables, and more.
- Create as many pages as you want.

This is great but the one I use for now is way simpler ( http://yanobs.com/notepad ). It is only an online notepad, not a wiki, and that is all most users need I think.
cool
