I send a weekly email (usually on Fridays) containing a few paragraphs with my thoughts and a list of my upcoming tours, presentations and other events. The message is sent using Google Groups, and I am the only person who uses it (replies go to me and not the entire group).
Click the button below to request being added to the group. Note that unsubscribing is easy and the link to do so is at the bottom of every message I send.
