Users in Mile Tracker are organized in groups and, optionally, subgroups. Individual users still need to create a group for themselves. Name it any way you want.
An organization can use a tree of nested groups such as departments or business units. Each subgroup can have its own subgroups without limit on how deep the tree goes.
Each group has settings shared among its users such as language, currency, date and time formats, plugin selections, and many others. These are set on the Group settings page (the Group tab in black menu). Perhaps, most important settings for new users are tracking units and unit decimals that define what Mile Tracker actually tracks and how.
Here are some common scenarios:
A single user creates a group for self. This group consists of one user and holds configurable settings for the user.
A small company normally uses one group with company name with all users in it.
A large organization uses a tree of nested groups.
