Group chat

In addition to 1on1 chats between to users, VNCtalk alos provides conversations with more than two participants in chatrooms or group chats

Start a group chat

When you add another participant to an active 1on1 chat, the interface for creating a new group chat opens automatucally.
Alternatively you can also start a new group chat from the recent conversations list and invite the desired participants:

New group chat Invite contacts (1/5) Invite contacts (2/5)
Select New group to create a
new group chat after tapping the speech bubble icon in the lower right corner of the recent conversations list.
Like when creating a chat, you
can select the desired contacts directly from the recent conversations list
or look for contacts via search bar.

In the next example, we start a group chat with three participants, by first inviting ...

Invite contacts (3/5) Invite contacts (4/5) Invite contacts (5/5)
... Chris via contact search ... ... and second Bob from the recent conversations list ... ... to the new group chat.
By tapping the (-->) icon , we create a new group chat.
Change title (1/2) Change title (2/2) Group chat created
Next you have the option
in the respective input field
to enter (optional)...
... a title for the group chat.
Finally tap on the checkmark icon to create the group chat,...
... which afterwards directly opens its chat window.
Group chat interface Group chat interface
Compared to 1on1 chats,
group chats can be recognized by:

(1) the group icon, which
replaces the profile picture(avatar),

(2) the title, which, when not
assigned, is set by a generated string.

(3) The group chat menu does
contain the option Leave
instead of Profile and Block user.

!!! tip "You can only leave a group chat by selecting the chat menu option Leave conversation. If you e.g. leave the group chat using the back ( < ) button to the recent conversations list, you stay a participant of the chatroom.

Group chat settings

While the available options in the group chat settings are not different from the 1on1 chat settings for invited participants, the creator, respectively owner of the group chat has additional settings options:

  • Rename chatroom: The owner can change the title of a chatroom/ group chat, as illustrated below.
  • Persistent room: If this option (switch) is activated, the group chat stays alive, even if the last participant has let the chatroom.
    When this switch is deactivated, the group chat will be automatically deleted from the server, once the last participant has left the room.

    In order to delete an obsolete but permanent group chat, the owner of the room has to enter it again an turn off the switch Persistent room. This will delete the chatroom from the server as soon as it has no members anymore.

  • Publically searchable: By activating this switch, the owner of the chatroom can make the group chat visible for uninvited users or, by deactivating it, hide the room from public search.

Settings: Chat info Rename chatroom (1/2) Rename chatroom (1/2)
The owner of the group chat has additional settings available.
By tapping the settings option Title of the conversation, the chatroom's title can be changed by the owner. ... The new name will be visible afterwards for all group chat participants in the changed title bar.

The menu item Participants provides the list
of all current members of the chatroom.
As owner of the group chat, you also have
the option here to invite additional users to
the chatroom.
