You can access the Tags screen by choosing Tags from the Posts widget in the sidebar
The Tags screen looks like this:
Add New Tag section is at the top of the screen. To add a new tag enter the Tag name and Tag slug and click on the Add Tag button. The tag name can be the full name of the tag to be used, for example "wedding". The slug will be a search engine friendly version of the tag. If you do not enter the slug the system will automatically create one consisting of all lowercase words separated by a hyphen, for example "wedding ".
On the right of the screen is a table that lists all of the tags in the system. Clicking on the tag name will take you to the edit tag screen for that tag. Clicking on the number under posts will take to you to the Edit Post screen with a list of posts assigned with this tag.
Placing the mouse over the name of a tag in the list displays a menu of options as previously explained.
The Bulk Actions menu functions as previously explained.
