The site is now running in secure mode (the so-called https) by default. This will improve the security of all the transmitted data, and ensure that the pages can't be tampered with.

The Head-To-Head mode will be disabled for the next few weeks, as it's not yet fully compatible with these changes. We will restore it as soon as possible.

These changes may not be compatible with some very old browsers, if you're still using one of those, we strongly recommend upgrading.
