If you are researching and preparing messages on a regular basis you have to check out: Google Notebook
This is a great resource for anyone researching on various topics or subjects online. Create a different notebook for each sermon or topic. Keep all the information, websites, images, or select-copy-add anything you need and access it from any online computer.
I don't normally blog about technology, but this has great potential for those of us who are keeping several months worth of speaking topics on the back burners.
They have even created an add-on for Firefox users.
