Hello,

Regarding the mybugstemplate parameter:

The standard advanced search, saved under "my bugs", lists all bugs withouth
any constraints regarding email and numbering. It happended that I could
change this standard search in the UI of a user.

I don't know how it was possible to change the "my bugs" standard search as
there is no "save the changes" button.

Can you tell me how and why it was possible to change the "my bugs" standard
search in the UI of a certain user?

---------------------------------------------------

Regarding the groups:

Is the group functionality used to make groups of users or groups of bugs?

---------------------------------------------------

Regarding the reports


http://www.bugzilla.org/docs/2.20/html/reporting.html

Do you know a good page giving some examples or explaining the report
functionality (or other functionalities of Bugzilla) in more detail?

How to generate good reports?

With best regards,

Christoph
