toodledo.com – online task lisk

www.toodledo.com  is a regular online task list but pretty complete and simple with free basic functionality.

An extra thing I like about it is that you can print your task list and create a booklet. it prints it out in the right format so you can cut it and form a booklet. There lots of other things including the iphone interface

I was going to write one myself and found this neat tool that saved a lot of work. SSHTM for Mac OS X allows you to create and mange SSH Tunnels.
