mod/termreview/tutor
Tutor groups are identified by a function in locallib.php. By default, it checks for the system at my college- a '/' somewhere in the shortname designates a tutor group. This can easily be changed- it is right at the top of locallib.php. If you just want to designate your tutorgroups by something ither than a '/' in the shortname simply change the / in
if(strpbrk($course->shortname,'/')){
to whatever you like (can be as long or short as you like). shortname can be changed to fullname or idnumber (or any other property, but these 3 are the most likely)
If you only want the class teacher or personal tutor functionality, replace
if(strpbrk($course->shortname,'/')){
with
if(true){
for everything to show as a tutor group, or
if(false){
for everything to show as a normal class.
You can also overwrite the whole function with any php function that returns true for tutor groups and false for everything else.
