I encouraged my wife (Hack) to Login this Weekend {had been months ago} using her iPad.
Odd thing with US Women's Tourney this week, she's a tad miffed that unlike her Laptop browser UI, there is no selection for Girls.
I realize mobile support is new, but I had no answer as to When?
So, next best thing is come here to Post.
[Fwiw, unable to Login to Forums to post since Safari (nor Chrome) support Flash]!
