Google Apps consists of a set of loosely coupled services that can be more or less assigned to a custom domain name. The current set includes email, calendaring, very crude web page authoring and serving (limited file services), and Google Docs. There are also less well known mobile services for Google Apps.
It's great only because it's free. Mostly it's unfinished. It's not at all obvious how one provides users with any kind of unified view of available services.
Turns out, you're supposed to edit the header of the "start page" associated with every Google App custom domain -- for example: MN Sepcial Hockey Personalized Start Page.
Yep, the header. The gadgets don't quite do the trick.
It's very crude, but it's at least understandable.
I do hope Google returns to Google Apps one day. They're only half-way to a 1.0 release ...
