>Groups allow the administrator
to isolate bugs or products that should only be seen by certain people.
There are two types of group - Generic Groups, and Product-Based Groups.
</P
><P
>&#13; Product-Based Groups are matched with products, and allow you to restrict
access to bugs on a per-product basis. They are enabled using the
usebuggroups Param. Turning on the usebuggroupsentry
Param will mean bugs automatically get added to their product group when
filed.
</P
><P
>&#13; Generic Groups have no special relationship to products;
you create them, and put bugs in them
as required. One example of the use of Generic Groups
is Mozilla's "Security" group,
into which security-sensitive bugs are placed until fixed. Only the
Mozilla Security Team are members of this group.

>XXX is this still true?
"usebuggroupsentry" has the capacity to prevent the
administrative user from directly altering bugs because of
conflicting group permissions. If you plan on using
"usebuggroupsentry", you should plan on restricting
administrative account usage to administrative duties only. In
other words, manage bugs with an unpriveleged user account, and
manage users, groups, Products, etc. with the administrative
account.</P

>In future, when you create a Product, a matching group will be
automatically created. If you need to add a Product Group to
a Product which was created before you turned on usebuggroups,
then simply create a new group, as outlined above, with the
same name as the Product.</P
