Reporting broken links
This page is for reporting broken links. If you only want to send a message about a link, e.g. because it seems to be inappropriate etc, then use the contact form here.
Before you click the Report Link As Broken button below, remember that 9 out of every 10 links that are reported as broken by users aren't broken at all! The reason they appear to be broken is that the user often has not got the correct "plug-in" (a free piece of software designed to help you see a picture or play a game) installed on their computer. Here are links to the plug-ins you'll need if you want to enjoy the majority of the super sites we link to.

Java
