For your privacy, and in order to avoid sending massive amounts of public updates (hopefully someday??) all functionality is implemented via 'Direct Messages', which are a private account-to-account means of communication. For direct messages to work, two things must happen:
To send a request, you send an SMS message to 40404 (Twitter's "phone number") starting with "d PilotTools ..." That tells Twitter you're sending a direct message (d) to @PilotTools.
This isn't all I have planned. I have TONS more ideas, but feedback and suggestions are always appreciated. On my list is a 'SUGGEST' command so users can propose things when they think of them. And with a 140 char limit, 8 of which are used by the command they'll hopefully be easy to read and very to-the-point (which make the best feature requests.)
