In Mathematica 7.0.1, from the menu select Edit > Preferences.  Select 
the Appearance tab and then its Numbers tab.  On the Formatting tab 
there, you'll see an option "Digit block separator". You may change that 
to a thin comma, a comma, or a period.

The same option may be set directly in the Options Inspector.  Search 
for NumberSeparator there.  If you change from the default, 
\[ThinSpace], you can opt to set this just for the current selection, 
just for the current notebook, or globally.
