http://www.maxpower.ca/wordpress-plugin-subscribe-to-commentFeatures: Easy administration via Admin menu;Displays all subscribed individuals and the posts they are subscribed to;Show basic stats wherever you like using a function call;Optional insertion of subscriber statistics into the Dashboard. Installation: Download the Zip archive and extract the entire directory to your local disk. Upload the entire directory (dash-note) to your plugins directory (wp-content/plugins/). If completed correctly, your directory hiearchy should look like so: /wp-content/plugins/dash-note/. Usage: Simply activate the plugin in the administration back end go to Options -> View Subscriber Info. The first time you generate the report, the statistics will be off. This is a limitation of the current design. Reload the page to see the numbers. As well, anytime you want to update your stats, you need to regenerate the report by going to Options -> View Subscriber Info. In this version, the logic is all backwards. So if you want updated to the minute stats you need to load the page twice. If I get around to making this plugin better, I’ll fix to logic to first generate the stats and then display them, not the other way around. See the screenshots below.
