A quick way to share your stacks with others (or others with you!) is through a unique QR code. To open a stack this way, click on the QR code reader icon in the top menu bar of the LTB App.
Say you organise a meeting and want to provide attendees with the agenda and supporting documents. And you want them to share their own presentations and materials before and during the meeting. You can use the Stack Editor to create a new stack for that particular meeting and put the automatically generated QR code on the meeting announcement. If you wanted to discuss certain aspects of the meeting such as time or location, just enable the chat feature for that stack.
