The best place to hide something at my house is in plain sight. Turns out challenges I was having making postings from my iPhone was a case of the same thing.
When the dialog box came up talking about XML and PPC and lots of other letters and numbers, my simple automatic-transmission mind locked up. That is until my good friend Paul Boomer set me straight. I thought it had to be some kind of setting deep in the code–scarry to Mr. Big Picture. Turns out I was, as is so often the case, over-thinking the problem. Two check boxes later, my iPhone connected and now you are reading this.
The ability to post on the fly was the one remaining capability lacking from the bad old TypePad days. Thanks Paul for your help and for not making me feel like an idiot. (Far better at doing that myself.)
