The reputation system in the agent now has two new modes:
Recs/Noise and Clicks/Noise

I think these ratios are a more accurate reflection of real reputation. They'll help you keep track of users who make rare but useful recommendations. I'm still defaulting to total recommendations. One reason is that people with a very high signal to noise ratio probably don't post often... Tell me how well they work out for you.

Note: You CANNOT artificially inflate your signal to noise ratio by deleting old recommendations.
