Because nobody was around at that moment. There is no paid staff waiting on-hand to provide instant replies. The tutors are all volunteers who surf by when we can. Many of us work, some of us live in very different time zones (so may be sleeping at the moment), and at least one of us (me) was off having lunch. You should be prepared to wait hours, if not days, for an online reply.

Meanwhile, when were you planning on posting the requested information?
