Lay out your site the way you want it. Set the URL of any post, page, tag or category to anything you want. Old permalinks will redirect properly to the new address. Custom Permalinks gives you ultimate control over your site structure.
This plugin is only useful for assigning custom permalinks for individual posts, pages, tags or categories. It will not apply whole permalink structures, or automatically apply a category’s custom permalink to the posts within that category.
