Nevermind...

For Objectis' final introductory e-mail, instead of saying:

Welcome to Objectis, go to your new web site http://w5how.objectis.net (your password to access the management screens is ********.)

...a better introduction could have read:

Welcome to your new Objectis site!

To edit your pages, go to your new web site at http://w5how.objectis.net and log in with:

username: w5how password: ********

Click on tabs such as the welcome tab, then click the edit tab within the page to change your content. You will easily find several other features to explore from there.
