The rep system does not allow you to rep someone again till you have repped 15 other people first!! That is just nuts. I hardly ever use it to be honest but sometimes there is an exceptional post I wish to applaud in a special way. The rep system should allow that. Can it not be reduced to 5 people or be linked to a timer (ie you can only rep someone once a day/week)? If there is obvious abuse it will be just that, obvious. Otherwise it just remains a feature that will never get used.
