Based on feedback, the moderation team have elected to remove the "I disapprove" option on posts (or as it may also be known... to leave "negative reputation").
This will go into action in approximately 1 weeks time.
The ability to utilize the "I approve" function on posts (or to leave positive reputation to other users) will remain as it is today.
For users who have previously received negative reputation (displayed as a red box in your User CP
), sadly there is no simple way for us to remove those from the record, and thus they will still be listed in your total reputation count.
