I don’t use Facebook, but I am on Twitter. You can also email me. Links are at the bottom of every page. I assume you know how to use email and don’t want a patronizing webform. That said, I’m glad you are here. There are a few things you might want to know about contacting me.
If you wish to encrypt your message, use my PGP key. If you need to send me an attachment, I recommend one of the following formats; they are listed in order of preference. There are reasons I prefer these formats.
First, they are all open standards. Anyone can create software that uses these file formats, and many have. Because they are well-defined, I am more likely to see what you see.
OpenDocument Format is preferred if you intend to send me an editable document; however, be aware that your document may reference fonts I do not have. If fonts matter to you, PDF is almost always a better choice because you can embed fonts into the document.
If you need to actively collaborate on a document with me, Google Drive offers at no charge a suite of excellent web-based office applications designed with collaboration in mind. I use it regularly. That said, Google has been annoying me lately, to be polite, with their quite reckless disregard for privacy. Feel free to send me a recommendation, if you have something in mind.
