I know this was an 4/1 joke, but if anyone needs to archive email from a web based email
PrimoPDF is great! It installs as a printer in Windows so you just "print" to a PDF which can be saved anywhere on your comp and printed later if needed.
And just in the interest of balance, I recommend the open source PDFCreator:
