    I am investigating remote part-time employment opportunities and see Appen is well regarded.
    I would like to work off my laptop/desktop computer without having to get in contract with a smartphone/app to work with your company.
    Also I use yahoo for email and am wondering if I need to set up gmail to work with you.

    Please respond through my yahoo email.
