How can I access a website which only allows Internet Explorer users to view it?
You need to change the user-agent of your browser (sent w/ the HTTP headers of your web requests) to a compatible browser.
If you use Firefox, you can get the User Agent Switcher extension.
If you use Chome, you can get the User-Agent Switcher for Chrome.
Alternatively, you can also get a plugin to integrate Internet Explorer in the browser of your choice (such as IE Tab for Firefox, or IE Tab for Chrome).
