I think it would be even better to leave the list as plain text but add 
an edit link next to each person.  When clicked on, the edit link would 
change the HTML dynamically so that what previously appeared as plain 
text now appears as HTML inputs, and when the save button is clicked, 
the editing is saved in the database using XmlHttpRequest and the HTML 
inputs change back to plain text without having to refresh the page.  
This would be the way a next-generation Gmail-like web app would do things.
