Newsletter editors who don't have access to dedicated publishing software will appreciate Microsoft Word 2010s ability to split the pages in a document into equal portions. You can use Word's columns setting to edit the layout of the page so that text is displayed in four quarters. Once you've set the text to display in quarters. you can edit the column settings to add in lines between the quarters if you so wish.
Run Microsoft Word 2010 and open the document that you would like to split into four columns.
Click the "Page Layout" tab, and then click the "Columns" button in the Page Setup group.
Click "More Columns" and select four columns from the list.
Click "Columns" again, and then click "More Columns" and check the "Line between" box if you want to insert a dividing line between each of your columns.
