The plugin you brought to my attention seems extremely usefull. I am quite familiar with SQL statements (especially when I know the table and column names, otherwise al lot of reverse engineering has to be done first). But I am not a Moodle admin. I am a teacher, with only those permissions. I read the documentation, and it seems that I would not only have to convince our admins to install that plugin, but also create new roles with sufficient permissions for teachers to us it within their courses. I don't think I will be able to convince them .... But I'll give it a try anyway
Thank you for your time and input!
