Is there a plugin that can generate reports on which users or categories produced the most blog posts in a given time period?
I searched the plugin repository for such a tool, but most of what I found were Google Analytics-type services. For the purpose of this report, I'm not interested in pageviews.
This plugin comes close:
but it doesn't let me define the range -- it's only the last 12 months for some reports, and all-time for others.
