Abstract: A method to keep selected messages in a networked conversation thread includes receiving, from a first participant in a networked conversation, a selection of a first message to keep from a sequence of messages in the networked conversation. The method includes verifying that the networked conversation is slated for deletion at a selected time after the selection of the first message, storing the first message in a folder accessible to multiple participants in the networked conversation, and notifying a second participant authoring the first message that the first message has been stored in the folder and is accessible to the participants in the networked conversation.

Abstract: A client device receives an arrangement of at least a subset of participants of a virtual meeting. The client device additionally receives an audio stream for each participant of the subset of participants of the virtual meeting. For each participant of the subset of participants, the client device determines a location based at least in part on the received arrangement, and modulates the received audio stream of the participant based on the determined location. The client device generates a combined modulated audio stream by combining the modulated audio stream of each of the participants and plays the combined modulated audio stream.
