A device comprising:

• a memory that stores instructions;
• and
• at least one hardware processor configured by the instructions to perform operations comprising:
• receiving a request from a user to activate a new media collection, the new media collection to be accessible only for a default predetermined window of time and to comprise a default geographic boundary size for where media content for the media collection originates;
• receiving input increasing the default predetermined window of time that the new media collection is accessible;
• receiving input decreasing or increasing the default geographic boundary size for where media content for the media collection originates;
• sending the request to a server computer for activation of the new media collection including the input to increase the default predetermined window of time that the new media collection is accessible and the input to decrease or increase the default geographic boundary size for where media content originates;
• receiving confirmation that the new media collection was activated for the increased predetermined window of time and the decreased or increased geographic boundary size for where media content originates;
• and
• causing a plurality of content messages to be included in the new media collection and displayed in response to a request from at least a second computing device to view the new media collection based on determining the request occurs within the increased predetermined window of time that the new media collection is accessible.

A non-transitory computer readable medium comprising instructions stored thereon that are executable by at least one processor to cause a computing device to perform operations comprising:

• receiving a request from a user to activate a new media collection, the new media collection to be accessible only for a default predetermined window of time and to comprise a default geographic boundary size for where media content for the media collection originates;
• receiving input increasing the default predetermined window of time that the new media collection is accessible;
• receiving input decreasing or increasing the default geographic boundary size for where media content for the media collection originates;
• sending the request to a server computer for activation of the new media collection including the input to increase the default predetermined window of time that the new media collection is accessible and the input to decrease or increase the default geographic boundary size for where media content originates;
• receiving confirmation that the new media collection was activated for the increased predetermined window of time and the decreased or increased geographic boundary size for where media content originates;
• and
• causing a plurality of content messages to be included in the new media collection and displayed in response to a request from at least a second computing device to view the new media collection based on determining the request occurs within the increased predetermined window of time that the new media collection is accessible.
