// mail2() function call:
// The email name: i.e. the bit before the @ sign
// 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.
// A number specifying which top-level domain to use.
// 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 "".
// Finally, the text of the link, i.e. the name to be displayed to the user in the web page.
//
// Sometimes you might want to code a link in which the email address itself is shown as the visible text, e.g. nobody@fake.address9z.com.
// To do this, simply call mail() rather than mail2(). Only the first four parameters are needed.
