Here is a quick way to send text messages using Quicksilver, an amazingly powerful application. I have previously posted a text message script using curl and the command line, and a major complaint was that the method was too complex. I hope this one is a bit easier to complete. Once you get the hang of Quicksilver, you will be texting from your computer really quickly.

1. Download Quicksilver, and run through the setup.
2. Launch Quicksilver with your specific key combination.
3. Hit the "." button to enter the text input mode, and enter the person's cell phone number that will go to the cell provider's email gateway, and hit enter. For instance, for Cingular users it is nnnnnnnnnn@cingularme.com. A close-to-exhaustive list of provider email gateways can be found here.
4. In the second box, type in a few letters until you get to Email Item (Send Directly).
5. Now, in the last box, use the text input method again (".") and type in your messsage.

That's it! Additionally, I added an email address called "text" to my contacts in my Address Book to hold each person's cell phone email address. This way I can take advantage of Quicksilver's Address Book integration as well. The only real downside to this method is that the message is superimposed onto the subject of the email, so the text message can get somewhat bloated.

I hope this helps you quicksilver text messagers out there.
