You can replace orders for some units, but leave pending orders for
other units alone, by only including
unit sections for the ones
you want to change.
If you want to see what orders are queued, but not change anything send in:
begin 999 # whatever your player number is ... end
To change your email address, send in
begin 999 email firstname.lastname@example.org # give your new address end
As a security measure, the confirmation will be sent to both the new and old addresses.
To change the name of your faction, issue the
name order for the
faction's player entity:
begin 999 unit 999 name "Seekers of Fame and Power" ...
Important: Don't forget the
unit command for the player entity.
