After reading this news about Performancing Metrics, I'm not sure how easy things will be. I've been using Performancing Metrics for quite sometime now to track my blog/website traffic and Google AdSense clicks. In fact, through it, I was able to trace an attempted click fraud in my site and alerted Google.
Performancing now recommends current users to consider Feedburner as an alternative.
Thanks Performancing for the great service and may all future plans go well! I still hope you'll have more payment alternatives in your Partners program soon.
