Unmaintained [RainDigitalDesign] User Activity (Users Viewed, Viewing Thread) 1.1.5

This addon should be called "Users who have read this thread IN THE LAST MONTH". The description didn't say that the data is deleted after 1 month and no option to change it unless you want to mess with Xenforo settings that interfere with the whole forum behavior. This addon is useless for small forums that don't get tons of reads every month on every threads
