I initially planning to purchase three of the tier 1 plans to create separate spaces. It would be convenient and very helpful to have our own separate Workspaces and Projects sections to further categorize our individual work within our IKI, without having to purchase additional accounts or log in and out of different accounts.

It's nice to have the additinal users in our accounts,
But having our individual spaces and projects would provide us with an additional level of categorization even for our own accounts, thereby enhancing usability even further.
