The YouTube Plugin allows you to search YouTube, select a video from the results and add it to your post. You don't need to have a YouTube account. You don't need to edit the b2evolution HTML Validator. You don't even need to go to YouTube.com. It's all done from inside your b2evolution backoffice.

This feature is not supported anymore by Digg.com.

Digg.com is a social bookmarking and news site. Users submit stories, then vote on which stories make it to the front page. With this plugin you can add Digg buttons to your posts by just checking a box in the Write tab. Or change one setting and instantly add the button to all of your posts. You and your readers can click the Digg button to add your post to Digg. Once the post has been submitted, the button will show how many Diggs the story has.

Works with b2evolution 1.8 and higher (including 2.x).
