There are two ways to share Project Updates with people outside your workspace.
Global share link
Found in the page header on the Project Updates page. Creates one webpage containing every update in the log, in chronological order. The page stays current, so anyone with the link sees new updates as you post them. Use this for a partner or lender following the project start to finish.
Individual share link
Found on each update. Creates a standalone webpage for that one update only. Use this when the recipient needs one specific update, or when you do not want to expose the rest of your project history.
Both work the same way for your recipient: a webpage in their browser, no FlipperForce login required.
