##Primary Tag
Allows the user to designate a primary tag of the existing tags associated with a post
###Installation
Clone the plugin to your wp-content/plugins/ directory
###Usage
Admin Area
- An additional line is added to the Publish Metabox area that will display and allow you to assign the primary tag for the post.
- The primary tag must be selected from tags that are already associated with the post. You cannot mark a tag that isn't associated with post as a primary tag.
- If a primary tag is not set for the post or no tags are associated with the post, the primary tag will state "Not Set"
- If you removed the primary tag from the tags associated with the post, the post's priamry tag will also be removed.
- To set a new or change a primary tag, you should click on the "edit" link adjacent to the primary tag text, and then use the dropdown that appears to make your selection. Click "OK" to confirm the change, or "cancel" to revert back to the original state.
- The new primary tag is not saved until you save the draft or update the post
