invitation is required to join the organization).

messages to users and can do everything a normal user in the organization can do

of your message. Users can see all messages they've been mentioned in through
the Mentions link in the left sidebar or by using is:mentioned as a
filter or a search constraint.
/me is a reference to one's one name, often used to send status messages to
Zulip by prepending status messages with
/me. Status messages are usually
written in third person and notify other users about the status of a user, such
as if a user is away from the keyboard or busy.

Private messages are either one-on-one or group
conversations, and are only visible to recipients of that message.
The exception to this is that in corporate organizations,
organization administrators may be able to access to
private messages via compliance exports. In community organizations,
even organization cannot access private messages unless they are
listed recipients of the message.
Private streams are for confidential discussions and are only
visible to users who've been invited to subscribe to them.
Public streams are for open discussions. All users can subscribe
to public streams and discuss there.
An organization is a private chamber hosted on Zulip with its own users,
streams, customizations, etc. Administrators

receive all messages from the stream that they subscribed to.
A timestamp shows you the exact time when a message was posted. It is
located to the right of a message.
Topics are similar to conversation threads. Topics are used to describe the
general subject of the messages a user sends. Topics effectively ensure
sequential messages about the same thing are threaded together, allowing for
better consumption by users. The topics of messages can be edited as well as the
content of the message.
When a user unsubscribes from a stream, the user is choosing to
stop receiving all messages from the stream that they unsubscribed from.
Also known as filter, a view is an option for viewing different
kinds of messages, listed in the upper left sidebar, including sections
All messages, Private messages, Starred messages, and Mentions.
