Adding Users

First, to add the Twitter users you want to follow, click on the "Filters" option in the main menu. Then, you'll be greeted with a menu like the one below:

Click on the "add filter" option. You'll then see a menu where you can view how many active Twitter users you've added and how many more users you can add in total. Click on the "Enter Twitter Handle" option. Then, add the users you want to follow without the "@" symbol, for example: "elonmusk," not "@elonmusk." If you'd like, you can add multiple users at once by listing them one below the other, as shown in the image below.

After that, if the user exists, you'll receive a confirmation message that they have been added. However, if the user doesn't exist, if there's a typo, or if you're trying to add the same user more than once, you'll receive an error message.
