You can do this to make it easier to find threads you want to check up on.
To subscribe to a thread you go to the thread tools and click subscribe on the roll down menu. Then go thru the steps.
At the top where it says Welcome and your user name there is a drop down menu that says Quick links click it and under Miscellaneous it says Subscribed threads click on that and it will take you to the page with all of your subcribed threads on it.
