Two calendars for some users

Two questions.First:

I want to create a second calendar for some users in a Notes Domain. No problem, just create

a database with mail6.ntf as the template. But I also want that these extra calendars can

“communicate” with C&S, however without creating extra users in the Domino Directory.

How can I do that?

Another question:

Witg the Lotus Script code I am able to open a user’s mailfile:

REM Select a user from the Domino Directory:

NotesUIWorkpsace.PickListStrings( PICKLIST_NAMES )

REM Get the registrationserver:

reg.RegistrationServer=curdb.Server

REM Get the user’s registration info:

Call reg.GetUserInfo(username,mailserver$,mailfile$,maildomain$,mailsystem%)

REM this is the user’s mailfile:

Set maildb=New NotesDatabase(curdb.Server,mailfile)

This is working fine, but see my first question: How can I get the user’s second calendar?

Both Lotus Notes and Lotus Domino are 6.5.1
