Issue with Notes addition to job

Issue with Notes addition to job

hey we have a little issue

we need to be able to update every one when anything in a job is updated

we have got our techs to use the notes feature and have made our users do the same

when a user / requester adds a note he can click on email inform tech of note addition (see screen shot for what check box i am talking about)

however when the tech adds a note the requester will not get a email saying that a note has been added

is there a way so when a tech adds a note the requester is notified
and can we have the default with both boxes ticked (then the tech has to untick to make private ect...)

Cheers
Aaron
