After following the steps of the previous post: how to follow competitor followers, you should use the button in the bottom menu to select the followers you want to add to the competitors list. Previously you could have filtered the users by performing a search or filtering the results.
If the list doesn’t exist you can create a new one by entering a new name, description and the privacy of the list. You can easily create lists segmented by topics or geolocation with SocialBro.
