BuddyPress Activity tab displays the site wide list of status updates and other activity streams. This article explains you how you can get tags from each new blog posts activity and display the most commonly used ones.
Facebook tagging is the most common feature of Facebook. Whenever someone tags you, an automatic post is created on the your timeline and you get notified about the tagging. Tagged post is visible to the selected audience from friends, friends of friends or to public. Here in this tutorial I am discussing how you can control your Facebook Tagging and its appearance on your timeline.
Add tags automatically rather than manually. Using Automatic Post Tagger plugin by Devtard all you have to do is create a list of tags with related words for each of them and this plugin automatically adds relevant tags when a post is published or updated. Also it offers you the feature to import those tags which are already present in your database and assign them to all posts.
