NOTE: this template is optimized for the "One-third section layout" of a SharePoint page as shown below:

1) Create a new List from scratch and add the following columns:

COLUMN NAME	COLUMN TYPE
Title	It's the default Title column
MESSAGE	Multiple lines of text
TIMEDETAILS	Date and time
USER	Person with NO groups and NO multiple choices
MESSAGEURL	Multiple lines of text
SUBJECT	Single line of text
IMPORTANT	Single line of text

2) Create a new List view and provide a custom name. For example: "News View"

3) Open the list settings (gear icon at the top right corner). Make sure that all the columns of the previous step are enabled with a checkmark. Then, go to the Views section and select the custom view that you've created in the previous step. Scroll down to the "Sort" section and apply the settings as shown in the image below:

4) ACTION: Create item
