WordPress Dynamic links

Dynalinks adds a simple link-management feature to WordPress, in which paths to links to other pages within the site are only created when the page is displayed. This means links won’t become dead when pages are rearranged in the structure of the site.

To use the plugin, simply upload it to the plugins folder within wp-content, and activate from within the plugins admin panel. When creating a link in the rich editor, simply use the URL:
link:82
to link to the page (or post) with the ID 82. These can also be entered from the code view in the editor as the target of a link, as any other link.
