So the premise is simple - if you like a post and want to give some positive feedback you can do so - and vice versa.
The points gathered from your posts contribute to your over-all reputation so over time, you will build up either lots of positive feedback, neutral or negative. This will hopefully promote more constructive discussion.
The reputation scores are classed as follows:
Forum reputation = poor = -50
Forum reputation = not so good = -25
Forum reputation = neutral = 0
Forum reputation = good = 25
Forum reputation = excellent = 50
There are daily limits placed on how much feedback you can give. There is a maximum of 50 +ve and 25-ve votes you can place per day.
As with all new features, we will be monitoring its effectiveness over time and tweaking where required.
