Text Size

If you find that the text on this site is too small or large for you to read comfortably, you can change it to a size more suited to you by doing the following:

  • If you use Mozilla Firefox or Internet Explorer for Windows, click 'View' then select an option from the 'Text Size' menu.
  • If you use Internet Explorer or Netscape for Mac, click 'View' then select an option from the 'Text Zoom' menu.
  • If you use any other Mozilla browsers click 'View' then select an option form the 'Text Zoom' menu.
  • If you use Safari on the Mac, then select 'View' and either 'Make Text Smaller', or 'Make Text Larger'.
  • If you use Opera, use the 'Zoom' options

Most of these browsers also allow you the press 'Ctrl' or 'Command' and either '+' or '-' to increase or decrease the text size. Also, on mice with a scroll wheel, pressing 'Ctrl' or 'Command' and scrolling the mouse wheel will also have the same effect.
