The requester's access to content available in the electronic chat room being limited based on the selected access control level. Related methods, apparatus, and systems are also described.

Abstract: A method for communicating in a digital conversation is implemented on a computing device and includes: receiving an interactive contextual emoji from a first digital conversation participant to post in the digital conversation with at least a second digital conversation participant, where the interactive contextual emoji is pre-defined to indicate at least a current availability status associated with the first digital conversation participant, requesting the current availability status from a status application based on at least an indication of the interactive contextual emoji, where the status application maintains the current availability status, receiving the current availability status from the status application, and displaying the interactive contextual emoji in the digital conversation with at least an indication of the current availability status.

Abstract: A computer system receives data that includes indications of a plurality of agenda items that correspond to the group event. During the group event, the system captures, by a media recording device, media data, converts the captured media data to a searchable version of the media data and searches the searchable version of the media data to determine a first time frame of the media data that corresponds to a first agenda item of the plurality of agenda items. The system displays, in a user interface that is accessible to at least one user associated with the group event, the representation of the media data. A first portion of the representation of the media data that corresponds to the first time frame is visually distinguished from at least a portion of the representation of the media data that does not correspond to the first time frame.

Abstract: A communication system and related methods are described. The communication system includes a communication server computer and multiple user computers. The communication server computer maintains synchronization of multiple copies of a graphical user interface (“GUI”) presented by the multiple user computers. The GUI implements a multi-user, digital communication environment and includes a chat area where communications are organized by time and a document editing area where communications are organized by subject. The GUI enables integration of the chat area and the document editing area and allows users to communicate across multiple communication modalities seamlessly and in real time.

Abstract: In accordance with an embodiment, a method is provided. First text is obtained by speech-to-text conversion of speech of a first participant of a collaboration event. Second text typed by a second participant of the collaboration event, who is connected as a text-only participant to the collaboration event, is received. A meeting thread is generated in a message space of the collaboration event using the first text and the second text. The meeting thread is provided for display on user devices associated at least with the first participant and the second participant.
