I've written a script to analyse all the course logs (generated via Reports > Logs) to get statistics on what each user has done. But the only way to identify which student each log entry relates to is via the "User full name" column. This is not reliable: we have two cases in our course in which two different students have the same full name. It's also difficult to cross reference information from the log files with information from other sources, like University enrolment, as there's no unique common key. In the case of the two students with the same name, you can't even use the Participants dropdown to select which you want, as the entries are identical in the dropdown.

Please could a more reliable identifier be added, such as username?
