Welcome from me too.

Remember to enable email notifications or you might miss any replies to any threads you post in. On the dark bar at the top of the page go to 'profile'.
Then select any of the pull down options.
On the header (just below the advertisement) on the far left hand side you will see 'profile info' and 'modify profile'.
There is a pull down menu under 'modify profile' and from this you select 'email notifications'.
Make sure the email notification box is ticked.

If you tell us the name of the person you wish to contact one of us can contact them on your behalf if you wish? However sometimes if the thread is really old and the member has not been active, or they they may have changed their email address so may not be contactable. I hope this is not the case here.
Good luck.
