Enwoven lets you simply capture and share institutional knowledge in a multimedia platform.
You can open your collection to public contributions, which you approve or deny at your convenience.
To enable this feature, open your collection privacy settings.
Below the general privacy options, turn on the switch "Open to public contributions." This will activate an "Add content" button on your public facing collection.
Whenever a contributor uploads a memory, it will show up in a "Review Contributions" section and you will be notified via e-mail to approve (or deny) before the content becomes a part of your collection.
