I have had the same with TH. We agree on a lesson time but, of course, the site will not allow the exchange of information like addresses or telephone numbers until the parent has bought your details. Often you hear nothing more, or the parent claims the site will not allow them to do so. I wonder if something is wrong with the TH website. Since September, I get one or two notifications of potential students in my area per week, or a message telling me that someone has 'viewed my profile', to which i always reply, only to hear nothing more. I had one courteous reply from one of these, telling me that they had been looking for a tutor at the beginning of the last academic year, when their son was in Year 11. This made me look at some of the other recent notifications I had had, and some of these parents had not visited the TH website for months, or even longer!
