hi,
i need some help in trying to locate where in the database the 'enrollment date' of the user is stored, or is it stored at all?

Y i need it is because im trying to modify the advanced upload of files in the assignment activity to include - enrollment based submission of assignments i.e.,
depending on the enrollment date of the student the assignment submission date for him/her is postponed appropriately so he gets the same amount of time to complete the assignment as a student who enrolled for the course before the assignment was posted.

(I hope i got that across clearly!)

As far as im aware there are two ways to enrol:
one, knowing the enrollment key or filling the form.
two, the admin includes u as a student (assign roles)
(if there is any other, do let me know!)

so, i need to know the enrollment date, or is there any other way of getting around it?

any suggestions are welcome!
