Allows users to configure a reminder for if they haven't blogged in a while.
The plugin checks all users on a twice daily basis using the WordPress cron system.
At the moment the plugin will send a reminder every 12 hours once you have gone over your configured reminder level.
To customise the plugin for your site then you can filter some of the settings by creating another plugin. If you want to change the maximum threshold value to allow shorter or longer reminder periods then use the 'pjw_blogminder_maximum_threshold' filter.
