## Fleissner attributes
Peter Fleissner attributed the following features to a MUD, similar to the [[Virtual Worlds#Attributes of Virtual Worlds]]:
* **Allocation of an identity**: Each user has to choose a name by which she can be identified. The procedure is similar to the log-in procedure at a terminal. In many MUDs, the person logged in is allocated to some collective body as well, like a guild or a professional organization.
* **Orientation feature**: The users are able to "look around". By typing "look" on the keyboard they can read a verbal description on the screen. By typing "who" they are informed who else is sharing the same "place".
* **Movement feature**: Usually the users may move freely within a kind of three-dimensional space (the directions are the four points of the compass plus "up" and "down")
* **Communication feature**: The users can exchange (written) messages and thus communicate with each other.
* **Action feature:** The users can perform certain actions, like grasping an object or taking a weapon.
