I think I have done this once, get the course full name in the Email subject in stead of the course short name.
However, I can't seem to find the right variable. In the language file, under forum, you can find this:
{$a->courseshortname}: {$a->subject}
However, changing $a->courseshortname into $a->coursefulllname or $a>coursename does not seem to work.
What is the correct variable to do this?
