It's really hard to find! In your downloads page, do you have a User Registration Solution Pack? I think they provide that when you buy the Security Assist Extension.
Downloading that will give you a zipped folder called 'UserRegistration100', and in that there is a Database folder that contains the Users.sql.
The Sql contains just one table (users) so you should presumably dump this in to your BlueSky database.
It would be easier to all if a copy of this were in the Data Assist support files. If you can't find it I'll provide you with it, but it should be there
