How do I send SMS from Empathy?
This option is always greyed out, even when I choose "new contact" and enter a phone number. I've tried "Normal" format, as well as "+12345678900" format, but nothing lets the "SMS" button become activated. I already have a Google Talk account, and have successfully sent and received SMS from it before, so why can't it just use that?
If it's supposed to use some proprietary protocol or obscure account type, then is it free?
