Spacing Issues on Signature Page
Highlight the text you are wanting to change then on the Home Ribbon, choose the line spacing symbol, select the desired spacing typically 1.5 for Thesis and 2.0 for Dissertations. Using the Add Space or Remove Space options as needed.
For the Signature page copying and pasting one of the signature lines is usually the easiest method.
Then removing any excess lines so the pages stays single paged.
