Ok… so I don’t know either how hard it would be, or if this is even possible…but
I think it would be an awesome idea if TE members could bookmark their favorite TE pages and access this via somewhere like the linkback dropdown.
thread tools → subscribe 
or del.icio.us on the linkback..
but doesn´t subscribe keep sending you updates. I mean more of a bookmark without the updates that can be kept on a per user basis. I don´t use delicious, and it would just be one more external thing to keep track of. I am really talking about something a little simpler that is more localized.
you can monitor the threads from the subscribed threads link. Its on very very top of the page from drop down links. Click on quick links > subscribed threads.
You will also be shown if there are any new posts just like it does in normal forum.
