Firstly, sorry for my english mistakes, i hope you will understand me even if some words may have no sense for you ...
Secondly, we all have known this moment when you read back your correction comment and discover that someone was not really nice (specially with new student) in his comment but didn't sign with his name and sometimes still put an Optimal mark. The new student most of the time will not complain because of the good mark and we can't do anything without a name (to referee to HM or MoM).
Could be good to have an automatic signature at the end of each correction comment, maybe if people are not anonymous anymore they will pay more attention to their comment impact.
