Groups trackers are trackers that can be used to:

1. Show a tracker item for each user from a group of users in the tiki site, while avoiding that other users can see other tracker items.
2. "register" an existing user to become a member of a group, as like an application form. This functions much like a User Tracker does.

In Admin>Login you can check the following:

1. Create the Groups
   Create a group as normal. see: Groups Management.
   Ensure that "User can assign to the group himself"
2. Create a tracker
   tiki-admin_tracker.php
   The tracker must contain a field of type user selector with the option 1
   If you want the items to be seen only by his user, you must set special perm on the tracker, as tiki_p_admin_trackers for the admin group.
   Even if there is no tiki_p_create_tracker_items for the tracker, the user will be able to create his item and to modify it.
3. Associate the tracker with a group
   tiki-admingroups.php
   You need to select the tracker and the fieldId of the user selector/option 1 field.
4. Save your changes in previous step, then add fields
   To be able to set the list of fields for the group tracker you must first save. Then you can decide if a field is mandatory or not, you can use this tracker as a mandatory set of new fields for registering for that group.
   Then each user of this group will have a tracker item that he will be able to modify from MyTiki.
   
   
5. Viewing, editing
   The user must have the group as his default group
6. Groups Tracker Permissions
   If the permissions are ok, the user can see his item in the group tracker with:
   
   tiki-view_tracker_item.php?view=+group
   
   If the item exists and the permissions are ok, you can see the user tracker of another user with:
   
   tiki-view_tracker_item.php?user=yyyyy&view=+group

You can set your fields to be "visible by creator & admin only", and the tracker field level, option "Field is hidden?".
This way, each user will be able to see his/her own tracker item through "My Tiki", but even if that user types the url of another tracker item (for another user), nothing will be shown at the tracker item level.

Note: a user can have many Groups Trackers associated to him. Each tracker must have a field of type user and option creator. To be able to see the item associated to the user (if permissions are ok) you can use:
tiki-view_tracker_item.php?group=xxx&user=yyyyy&view=+group - the group must have a user tracker
tiki-view_tracker_item.php?trackerId=yyyyy&view=+group - the tracker must be a user tracker
