After much procrastination I have finally made the domain switch over to paulturner.me.
All requests to the original domain paul-turner.net are automatically redirected to the correct page on the new domain with a “301 Moved Permanently” HTTP header.
This means that all search engine traffic should be preserved, and the links updated over time.
This was achieved simply with mod_rewrite and a single index.php page:
Please update your links.
