It is possible, but given the current implementation it will require more work than the leading zeros hack.
If the purpose is to separate participants in an activity wouldn't a designated "group" mode be better than personal groups?
Hi itamar,
Thank you for your fast reply. I was just curious, how to do this. At times I set up one student with one group for journaling with the database module or for access to personal files. As class sizes are small, I have no problem to do this manually.
With kind regards,
Hartmut
A private journaling application can be done in the dataform. What remains is restricting access to certain users. Currently you need to create groups and grouping for the designated users. But this should probably better handled by module restrict access settings (after all, grouping is essentially an access setting in the course level). If hacking I would hack the latter.
