Uninstalling

Deactivating never deletes anything. Deleting the plugin deletes nothing you chose or that proves anything unless you have turned on Delete the settings and the record when the plugin is deleted, and think before you do, because the record is the proof that people were asked. With it on, the settings, what is held back, the record and when you last pressed Ask everybody again all go. Either way, the last reading of your site and the monthly reading's note go, since they are no use without the plugin.
