Afriman - not everyone knows the meaning of PM = Private Message - and if you don't have your profile setup correctly you wont get email notification, so I would suggest - post a email, contact number and a URL to the live chat. (not that the chat is actually working). Most of the time you don't even see the 'notification" icon on the top for new messages.
I'm not a IT expert and also had some real difficulties when I subscribed to this forum. Maybe update your signature with some PERSONALIZED contact details. Obviously people who subscribe on this forum is not your every day customer - they "mean business".
Note: Sometimes the Chat closes quickly and other times it will wait long for someone to accept the chat. I dont mind holding, but HATE IT when it say "online" and I must constantly complete the form to start a new chat if no-one respond after 1min......... Just a suggestions.
