Email Templates

Does anyone know how to save an email template so that it's available via a
specific mailbox?

In outlook, I have my user mailbox [jbarrient] and a sales mailbox. I need
to create email templates that will go to the general public from the sales
mailbox. Two other users have access to this mailbox as well. When they need
to send an email they will use the email templates created. However, when I
create the email templates they exist in my local folder only and others
cannot use them as they don't have access to my local folder. Someone did set
this up for us before so that when i go to the sales mailbox, click Tools
Forms Choose Form and Look In: Sales, I can see the list of templates and
select the one i want to use. I need to add more templates to this list. How
can i set this up for other templates [oft]?
