Lifehacker is showing a great tip that I'm sure most people already know about. For those of you like myself who are a little late to the party here's the deal. You can send a PDF document to email@example.com and they will send you a text document in return. If you need HTML you can send it to firstname.lastname@example.org and you'll get an HTML version of the document. Pretty cool hack that could come in real handy for altering documents that were never meant to be changed!
