No need to be bookmarking that many threads. Go here
https://vborg.vbsupport.ru/profile.php?do=editoptions and under 'Default Thread Subscription Mode' select 'No Email Notifacation'.
That will subcribe your to every thread you post in. So when you come back, just click on the usercp link and if there are any replys, it will be shown in the usercp. This is how i keep up to date with all my threads and hacks.
