There's a difference between technical help and requesting a free piece of work.
While I'm not discouraging those who wish to volunteer on their own terms, there are also those on this forum who are professionals for whom the issue of what is known as 'no-spec' work is extremely contentious, and will have no qualms about telling you so, which makes this thread problematic.
I'm going to lock this thread so it's still visible. Anyone who wishes to do something for teachstudents may send a personal message and deal with this off-board.
Thanks.
