# Naming Conventions

These rules apply when naming users, groups, topics or queues:

- $ is illegal at the beginning of the queue or topic names—but legal at the beginning of user and group names.
- A user name cannot contain colon (":") character.
- Space characters are permitted in a description field—if the entire description field is enclosed in double quotes (for example, "`description field`").
- Both * and > are wildcards, and cannot be used in names except as wildcards.

  For more information about wildcards, see Wildcards.

- Dot separates elements within a destination name (foo.bar.*) and can be used only for that purpose.
