I've searched the forums and found information on how to do this and it is the same as what I had already tried, however after I save the moodle.php file then go back and check the message, it has changed part of the text but not all and $a is still there even though I have deleted it when trying to change the text. This is the text I'm trying to change in the moodle.php file, "This course requires an 'enrolment key' - a one-time
password that you should have received from $a"
Can someone please tell me how I can make it save the changes I'm trying to make and what does the $a stand for as it appears to be grabbing a persons name with an email address linked to it but I don't know why it is grabbing that particular person's email as they are not an Administrator or a Key Holder.
Thanks in advance
