More cool ways to use Remember The Milk
Mind Like A Sieve Yahoo! Widget
Graeme McCormack has developed the awesomely named Mind Like A Sieve Yahoo! widget for RTM. This handy widget lets you can complete or postpone tasks, or open them on the RTM website, just by right-clicking on the task name. The widget’s flexible display also allows you to customise which columns are shown (due date, priority, etc), change the column ordering, and sort by clicking on the header.

Remember The Milk with Launchy
Don Whitford shared a cool tip on the RTM forums: you can set up Launchy (a neat application launcher for Windows) with Twitter to conveniently add tasks to RTM with just a few keystrokes. Adam Pash at Lifehacker has written up a great article on using Launchy with RTM, Google Calendar, and other utilities. Check it out!
