I just thought I'd share with everyone a useful Website I've been using lately for bates stamping and marking PDF documents straight to download. It's called Web PDF Tools by Braintrade, Inc. It's fast, easy to use, and there is no login! The company is based here in Arizona. I have not looked at all of their features yet but I did experiment with a nice signature function where you can sign or capture a signature from your smart phone and stamp it right on the signature line of any PDF.
