On the ARM, you have the lists of authors who have modified your groups' repositories for each month. To see any of them, in the Authors section of your groups, you only need to click on the date at the top left and, from the drop-down menu, select the month you are interested in.

Thanks to this information, you will be able to know correctly which authors contributed in the month you need to know, giving us complete, correct, and fast information. We invite you to subscribe to our News channel to receive weekly short posts like this.
