Right, I found that, but I don't understand the instructions to edit:
To alter or translate this email, use the following links:<br /><br /> [<a href="phrase.php?do=edit&e[emailsubject][welcomemail]" target="_blank">Email Title</a>] [<a href="phrase.php?do=edit&e[emailbody][welcomemail]" target="_blank">Email Body</a>]<br />
<br />
Do I edit "email body"? I don't know what it says now.

Thanks Mark
