Is it modeled strictly per-user or is there any notion of an "organization" similar to Github? It's hard to imagine a business having to manage paying for a bunch of individual accounts so they can have access to the company's private repo.
Currently, private packages are only available for individual users, but support for organization accounts is coming soon. Feel free to create a user for your organization in the meantime, and we can upgrade it to an organization when support is here.
