To remind me of the things I still have to do, and to let you in on what I am thinking, here are some tutorials I was thinking about writing:

• Introduction to Ajax (ever notice how Gmail doesn't refresh the entire page when you click on links?)
• How to make an Ajax-based poll
• Updating/Adding a better PHP IRC Bot turorial. This would have more features and an easier way of making your own functions.
• Introduction to the Google API
• And more...
