Open your document processing software. Click "Format." A pop up menu will appear. Scroll down the list and click "Paragraph." Change the page alignment to "Center" and the font size to 18. Type the name of the seminar and the word "Sign-in." Press Return.
Click the word "Table" found along the top of your screen. Scroll down the pop-up menu, click "Insert" and "Table."
Select the number of columns and rows you want on your sign-in sheet. For example, if you are expecting 15 people, you will need 16 columns running down the page. Always select an extra column to incorporate the heading that will be written in the top column cell. The number of rows you use is determined by the information you wish to gather. At the bare minimum, you will need each participant's name and email address. Add rows to include the participant's address or phone number. The rows run across the page from left to right.
Click centered alignment and type the headings in the row cells. For example, type "Name" and "Email Address" in different cells at the top of the page.
Save the document and print as many copies as you need.
