if you are guest in the find option  

select 'all logbook'

it will display all 'attributes' from other logbook 
with no option  'guest command ...'
but having the same 'attribute' name

Solution :
**********
I use the copy to command to make a copy to other logbook
with option 'guest command' enabled

in this section I remove some field so the guest user can't no see all field

I suggest to give acces to 'guest' on a second run of elog to another
port or other computer ?
