We recommend separating your personal and work-related videos. The only difference between the two are the visibility settings you choose for each.
Step 1: All users begin with a Workspace. Add separate Workspaces in the left purple pane. Create Workspaces for projects, teams, departments, etc...
Step 2: When you create a weet from your team Workspace and share it with someone outside of that Workspace, that recipient does not get access to your team Workspace. They only get access to that weet video.
The weet will show up on the recipient's personal Workspace!
