Something I am not getting is how many databases are involved.  If
I have 2 databases and a database for shared users, is that 3, or
2 (one of which contains the user registration info)?

I am also not clear how much trying it out I can do without making
a big mess.  Any words of wisdom about that?  

Thanks,
