I love the whole corkboard / bulletin board concept and I'm surprised it isn't everywhere yet. This plugin allows you to embed a cool, interactive corkboard page into your site. It does exactly what it says it will.
Be careful, though because the example code provided here and on the main Padlet site is correct, but the example code provided with the plugin is wrong. The correct format uses the full word, 'wallwisher'.
