Delete COSA's email from COSA directory application

From IT director, having COSA's email visible could make us target of spam.

An option is to create a submit form that users can attach their applications and contact information.

Start by locating the COSA directory application and the code that displays COSA's email address. Confirm where the address is exposed, then determine whether the requested submit form is part of this issue or only an alternative; done means the email is no longer visible and the agreed application contact flow is represented.
