Hi,
I'm new on here too and still learning, but check your height requirements. I'm not getting many matches either, but when I checked out 1 of the 'about me' tabs it had a default of 'his' height matching mine being very important - I'm 5''1, the chances of a guy being my height is relatively slim. When I changed it I did get a few matches. Just a thought, hope it helps.
Unless something has changed, the height setting was just used for flex matching. I wish eH had used a height setting (where you could set a range like your age) as a primary match setting when I was a member. I think it would have helped me out.
