    How to change the text box field size?

    Asked by elron on January 02, 2016 at 10:05 PM
    One last small item. The text field under "How many books are you showcasing on your Author Site" is too wide. I have tried to make it smaller using the the "Size" button in the tool bar, but no matter how many characters I set it to, the size doesn't change. What am I doing wrong?
