Thunderbird : Saved Search

Taken from the Thunderbird : FAQs : Saved Search - MozillaZine Knowledge Base. In short, thunderbird allows a person to make a folder that have messages from people or subjects or even dates in 100 different folders. IE I can have a Joe folder, a James folder and a Mom folder, and still have a 'Family Search Folder' that combines all of them. That way I could read just Joe's email or if I wanted to see something the entire family is talking about I could switch to the 'Family Search Folder'. Neat.
