You can subscibe to any thread that you choose and you will get an email letting you know someone has posted.
Also instead of looking thru each thread try the new post button on the top of the screen in the navigation bar, that will only show the threads that have changed since your last visit... Once you have read all the threads that you want click on the quick links on the top nav bar then click the mark all post as read... When you come back the next time do that same process over again....
