Before you could tag your profile...
Now you can tag your articles too!
Nothing is easier than tagging your articles!
While publishing a new article, just add the subjects you want to tag right below your article:


Your friends will also be able to see what you've tagged.
They are posted in your profile column, right below your Info.

By clicking on a tag, you will see all the other articles tagged under the same category. Now you can quickly find all the articles that discuss the same subject.
And what are you going to tag?
