It refers to the roles played by different types of user on the platform.

There are four types: Visitor, Member, Moderator and Administrator. Each one has different privileges, mainly related to the level on which they participate on the platform.

Your access to a group will be more or less restricted, depending on your user status.

Visitors have the most restricted access. Their participation will depend on the properties assigned to each tool. In many cases they will only be able to read the content of tools which are public.

Members have more privileges and Moderators exercise a certain degree of control over tools and the material published in them (for example, they can modify or delete entries in different tools).

Administrators can grant or withdraw membership and authorise the introduction or suppression of tools. They have total control over a group or a portal.

•  Visitor (not belonging to a group)
A user classed as a visitor (not a member of a group) can only access public groups or resources and the public tools of private groups. Visitors have restricted access and cannot, for example, play an active part in the different areas belonging to a group (for example, they may not be able to write comments in a blog, or send e-mails to the mailing list). Visitors often have permission only to read material.

•  Member
You have this profile when you have applied to become part of a group and the administrator has approved your membership. As a member, you will be authorised to use all its public and private resources.

As a member, you will be able to edit your profile and set privacy levels, determining which members of the group can see your details.

The permission you have for each tool depends not only on your user status but on the properties assigned to a tool by the administrator when it is created (for example, the administrator can decide whether members can write new entries in a blog, or whether they are free to post files in the Repository).

•  Moderator
Moderators have the same functions as members but with some additional functions: they can delete or modify entries to a blog, delete messages in a Forum, moderate the Mailroom, write items in the group's news and administer the content of the Repository, etc.

•  Administrator
The Group's administrator decides which sections and which material and tools will be included. The administrator sets the properties of the group and the tools (names, whether they are public or private), and appoints moderators. When dealing with tools the administrator has additional privileges to those of the moderator.
