Wiki

Hi all,
I am evaluating some wiki pages of my students and qualifications seem not to be integrated with the qualifications sections of Moodle. More, it seems that a message is sent to the author of the last version of the wiki doc, but it seems that some students have received lots of messages while some others have got nothing. I do receive all of them (maybe because I am the teacher), but in the message there is no indication about the page I am evaluating nor the group that "owns" that page. So,
- how can students know their qualifications ?
- how can I know which are the qualifications I have put to each group ?

Thanks
Bernat
