My pleasure. When you have to write something I can help help you with the English. I have year and years of writing experience. Usually best to send by word doc so I can edit in doc and return. Very short things like today can be fine by line. Part if my job was editing IBMBA business project papers for International grad students. But need plenty of notice and time. Next few days will send dome duper simple review power point. My feeling is the simpler it is the better the easier it is to remember.
