Virtual Inbox in Thunderbird

Right - I've finally figured out how to set up a virtual inbox in ThunderBird3 that centralizes messages from multiple accounts and folders into a single location.

1. Select an exsting folder on an existing IMAP account
2. From the menu select File > New > Saved Search
3. Decide where you want to keep the Virtual Inbox. It can't be top-level, so I choose Local Folders as the parent.
   
4. Name the folder, such as Virtual Inbox.
5. Use the Choose button to select the source folders of your messages
6. Select "Match all messages"
7. Done
