Impersonating users in SharePoint
I ran across this question in the newsgroups, "How do I impersonate one of my users so I can see what they see on their MySite?"
Well, if you are faced with a similar problem, you can use the RunAs command - runas /user:Linda1 "C:\Program Files\Internet Explorer\iexplore.exe http://localhost/myportal/" This works in WSS to see all the personalizations the user has done on their non-shared view of the page.
Another option is to go to the User Profiles Administration (SharePoint Portal Server only), find the user that you are working with, and click the drop down next to their name. In this drop down is 'Manage Personal Site'. This will show you their MySite.

[edit] - I've added a link to the RunAs command documentation in the Windows XP documentation. This command also works on Windows Server 2003
