One more question: In the documentation it says:

If you are using Pulumi in your organization, by default the stack will be created in your user account. To target the organization, name the stack using `orgName/stackName`:

Does this only apply to pulumi.com as state backend? If I try this with S3 backend it says:

$> pulumi stack init orgName/test

error: stack names may not contain slashes

hey! slashes aren't supported due to limitations on buckets. the solution is to use something like dots

projectname.dev

I see, thanks.

here's a quick video:

stack init won't allow slashes, but stack rename will (and converts them to dashes I think)
