When I post a link to comment on multiple diagrams, the subject line is always "Sebastian Fochler invites you to comment on 2 diagrams" in the mail. I do not think that's good, because then you can not read on the subject of mail, which topic or process it is. It would be good if in the window that opens, if I invite someone to comment, in addition to the addressee and the mail text could also enter the subject.
