You need to have this plugin is you want your users to add tags/keywords to identify themselves with. I aksed Oxwall Accessories if they could increase the number of tags as it was limited to 20 before. So they updated the actual plugin in the Oxwall Store for everyone else that would purchase it...they did it for free and within 24hrs, which is awesome. So the newly updated plugin allows the admin to set their own maximum number of tags. The prominent tags are highlighted to stand out which is a cool feature to have.
