A wordpress plugin to disable cookies for commenters and use local browser storage instead
Wordpress plugin that disables the cookies used to remember a commenter and instead uses local browser storage for that information and javascript to fill the form.
Just upload the danielfarrell_js_commenter folder into your plugins and Activate it in your control panel.
The reason I wrote it was I was looking for a way for a wordpress caching plugin to be able to cache pages for someone who had commented previously.
