I hope this is relevant to the dev list but if it is not please let me know.

I was trying to estimate active users out of our registered users. I ended counting users that had a job during the last month. How would you guys do ? 

During this process I also wanted to see how we were doing in comparison to other instance. I set up a simple survey and would greatly appreciate if instance admin would take 2 min to complete it. I will publish results here (or maybe to some more relevant place, let me know) at the end of the month.

Regards,

Philip
