Design a way for a signature box to be added into moodle 2.4.
I have a couple of examples of the kind of thing I need below, but whether it's a plugin or widget or whatever, I need it to be held within the architecture of moodle and the data kept within the moodle as well. The final aim is for students to sign to declare that they have done their own work, and for that to be kept within the moodle just like their assignments are.
