it would be great to set default values for 'Preferences' parameters
(for first time logged users) into GNUstep/Defaults/.GNUstepDefaults file
and use it inside SOGo.
I tried to write
SOGoFirstDayOfWeek = 1;
into .GNUstepDefaults and login as new user first time. I had my calendar
started from Monday, but when I called 'Preferences', there was
'Week begins on' set to "Sunday" and when I made some change
of some other settings, "Sunday" was saved into my 'Preferences' :-(

So it looks like SOGo Web 'Preferences' doesn't not use .GNUstepDefaults variables.

When this bug will be solved, could I set all 'Preferences' parameters in
.GNUstepDefaults file?

Thanks,
