Hi Mr. Fabe,   I want to tell you thank you very much for the solving of my paper. It is excellent.   Just I want to be sure at the end of making job description and job specification is it better to put the signatures same as the sample that I attached.   I already sent it to tutor but he gives as a chance for review it and sends it again.   I need your reply.   Thanks,   W.
