            Use this command in a course channel to increment the counter if the course is currently suboptimal for you. This command produces no output in that channel.
            It doesnt really matter if its because you forgot your laptop-charger or the course just changed its modalities and you turned negative without any way to become positive again.
            If you supply a reason it will be forwarded to fsinf to take a look at. (We want to know when you forgot your laptop chargers! XD )
