The review module, which can be found at http://www.pcplayground.com/reviews.html has been updated.

Previously when someone would click on a letter or number to see which reviews lie in that category, it would show a 404 page for them.

The links now work correctly.

This error came about when I changed the site to a more HTML based site. So has not been around for too long.

Thank you to everyone who told me about the 404 pages.
