Here is was able to learn in less than 10 min:
A. I Emailed to Lotus Notes --> The backgrounds does not make it through.
B. I emailed my GMail account, looked at the result on my ITouch. Impossible to read without zooming in. The font size appears to be 3 or 4. (not at all what the screen shot on the presentation page looks like).
C. Signature: Instead of appearing right below the text, it appears at the bottom of the Background. That is one page too low.
D. "Type your text here" --> Why do I have to delete it first. It should be automatic the moment I click on it.
Nice concept, but far from being ready/tested.
