I removed the instructions for Eudora Rescue since there's already an excellent README on the product website. Sorry I forgot to include this in the Summary field. --hao2lian

I am merely a lurker on this site. However have updated the page after a wonderful experience. After no luck at all migrating from Eudora to Thunderbird on WinXP using any Windows tools listed, I found a (kludge) solution that worked. I exported my Windows Eudora directory to a Mac, used "Eudora Mailbox Cleaner" (following the instructions) on the Mac and then exported the result back to Thunderbird on the Windows box. It worked beautifully... -Dan
