I KNOW most of you have Abode Acrobat installed on your home and work computers, but in case you don't, PDF Online may be the answer. "This site takes numerous types of documents – such as Word, Excel, or PowerPoint – and converts them into PDF. Just upload your original, give a name to your file, and enter your email address. Within minutes you’ll have a professional, secure, and portable PDF file in your inbox."
I tried it, and while it took longer than promised (maybe 15 minutes), it did work.
