I'm using this, and already doing something other then whats on the list, posting links online! Damn it! I can't win!

tasks

"Someone at Google finally realized how helpful it would be to add a to-do list to Gmail. It is called “Tasks” and is now available in Gmail Labs (click on the beaker icon next to “Settings” on the upper right hand corner of Gmail). When you enable Tasks, it appears as a link in the left-hand column under Contacts. Click on the link and a box pops up in the lower right-hand corner like it does with Gtalk. You can add tasks, reorder them, cross out completed tasks, switch to a new list, or pop out the box to keep on your desktop. It’s a simple feature, but really useful for people who find that they keep Gmail open all the time. In general, I’m not a big user of to-do lists. Not because I don’t need them (I do), but because they require that I open a separate application or go to a dedicated Website like Remember The Milk."

Plancake is a smart online task and list manager software.
