/*    
	1. The email name: i.e. the bit before the @ sign
	2. The second-level domain of the email address: this is the bit after the @ sign, but with the top level domain (".com" or ".co.uk" etc) stripped off.
	3. A number specifying which top-level domain to use. I list these below.
	4. The fourth parameter allows you to specify a default subject for the email, by passing e.g. "?subject=Changeringing", but normally you'll just need the empty string "".
	5. Finally, the text of the link, i.e. the name to be displayed to the user in the web page.
