Here's a tip that seems pretty obvious, but I've never used it before, and it's really useful, especially if you are going to hand code off to someone else to finish
Add a comment line to your code as follows
// TODO - Add a task to complete here
Then, go to the main menu bar, and select View - Task list. In the task list Window, there si a drop down list that says either Comments or User Tasks. Switch to comments. TADA! TODO!
Quick, easy, and professional! No more sticky notes or long emails about what is left to do. And it gets tracked with your source control so you can see who made the change and when. You are use isource control, right?
