Abstract: A method, to manage an event invitation in a computer network environment, comprises presenting, using one or more processors, an event invitation creation indicium to a first user on a user interface of a computing device. Responsive to user selection of the event invitation creation indicium, an event creation interface is presented to receive event details. Responsive to receipt of the event details, an event invitation message is generated for communication, via a messaging system, by the first user to a second user of the messaging system, the event invitation message including a join indicium that is user-selectable to join a group chat related to the event. Responsive to a message send input from the first user, the event invitation message is sent, via the messaging system, from the first user to the second user. A request is received, from the second user, a request to join the group chat related to the event.

Abstract: Embodiments for communicating and displaying collections of image and video clip content with an opt-out interstitial are described. In one example embodiment, a device receives interface information about a group of content collections from a server computer system. When a user inputs a selection of a first content collection, the device displays images and video clips in a sequence defined by the content collection. Each piece of content is displayed for less than a threshold display time. When the device finishes playing the first content collection, the device presents an opt-out interstitial. Additional content collections generated from content submitted by other client devices can be received from the server computer system, and are presented based on a response input, or a lack of response input, to the opt-out interstitial. Some embodiments include content collections generated by the server computer system, as well as advertising elements presented between content collections.

Abstract: In one or more implementations, user content items generated using a client application may be shared with users that are not contacts of the user within the client application. A user interface that indicates a number of recipients of the user content item may be generated that also includes a first section that displays the user content item and a second section to add text content to the user content item. In various examples, one or more classifications may be associated with the user content item.

Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing at least one program, and a method for managing chat conversation retention models. The method may include causing display of an interface that enables a user to select one of multiple retention models for association with an electronic chat conversation, and receiving, via the selector interface, a selection of a particular retention model. The retention model specifies an amount of time that each individual message in the electronic chat conversation is accessible upon being read by a receiving user. The method further includes storing a newly received message as part of the chat conversation, where the storing includes configuring a retention duration attribute for the message in accordance with the amount of time specified by the retention model. The method further includes erasing the message in accordance with the retention duration attribute.
