Hi Ruben, Couple of ideas come to mind: 1) User the referring page as an indicator for a custom signup page that uses it to determine the signup group to show. -or- 2) Define a variable (or re-use an existing one) that is passed to a custom signup page that uses it to determine the signup group to show. -or- 3) Do #1 or #2, but build the logic into a function that runs from the moodle link construct.
