I'm in this situation myself and I'm quickly reaching my breaking point. In one instance, I submitted an "exercise", which I spent ~six hours on, one week ago and haven't heard _anything_ back -- not even a confirmation that the submission was successful. I had been on the fence about following up, but fuck that, I'm going to do it right now. Thanks for the nudge. ;)
