If you go to your UserCP here:
http://www.ducati.ms/forums/profile.php?do=editoptions
and look at "Default Thread Subscriptions" I suggest you change it to Instant Email Notification so you know when someone has responded any thread you are involved in and will provide a link in the email to that thread.
Also when you visit the site if you click on the Quick Links pull down menu (up towards the top between the Log Out and Search) then click on Subscribed Threads it will show all your threads that you are currently subscribed to and what's going on in them.
That link is here also, just so ya know:
