Our server has been updated to secure against the heartbleed bug.
You can double check this here if you wish.
It is highly unlikely that any of our users were affected by this and there should be no need to change your passwords. However, if you feel like doing this head to the 'account' section of the menu when logged in. From there hit 'edit' underneath your username then enter a new password there.
