Jetpack,

That's a good question about the on/off. Bob asked me that earlier. I don't know the answer.
It's obvious if you know you can't go a particular day, you don't want to be texted that it's blowing. It'll just be annoying and cost you, too. The next day, maybe you would want to "switch it on", like you said.
I don't have an acc't or text service. Can someone else figure out some more of the specifics in that regard and post about it.

Also, as you said, texts can be read as well as made - online - without the need for texting via a phone. This app seems like a winner at first glance.
We will know before too long.
