The install process is pretty simple in most cases. I suppose what you need is a client install, in which case you'll need to get the logon parameters from your friendly admin (server name, your Notes ID name, the ID file ideally, sometimes the IP address of the Notes server).
When you have all those details, you can just launch the install process and answer the basic questions and you'll be done.
As for the Inbox, that is part of your mail database and will automatically be installed with the rest of the Notes client.
Hope this helps.

I've got nothing to hide, and I'd very much like to keep that away from prying eyes.
