I'm not sure if this is a bug or a bug fix. In PR6, when a new user is created, you were allowed to specify an existing home space for that user by selecting the existing space underneath Company Home and leaving the "Home Space Name" field blank. In the RC1 release, when performing the same steps using the New User wizard, a selected sub-space is not recognized, instead the user's home space is "Company Home". I preferred the PR6 behavior where I could associate a user with an existing sub-space as their home space. I must confess this was used as a workaround to role based permissioning though.
