hello how are you i really need help !!! is to to let the users on my wesite to post in forum section their .rar files because my website consist files sharing for programing cars purposes and PM messages privet messages thanks ...
For PM'ing private messages you can add "Chat" app. Adding files is not possible yet, but will be in the future. For now I would recommend to use any free file hosting service and just paste the links in the threads ;)
