I'm not a big fan of them, but have been getting them for years from a couple of clients. I told them this was for them and it didn't do anything for me except take up my time. But I do accept them.  It would better if I didn't have to respond or correct their grades every single month. I'm just so glad we don't have the monthly calls anymore.  Those were a big waste and the same exact conversation over and over again.  Grrrrr...
