Passed on from the BPL Web Team:
"There is a subtle, but new feature in the BPL.com forums.
If you visit the main forum index page, and the thread index page (the one you get when you click on a forum from the main forum index page), you'll see numbers in parentheses that indicate the number of new threads, or new posts, since your last visit.
Then, when you enter a thread to view messages, you'll see a subtle red "NEW" tag associated with those new posts.
Also, on the forum submenu at the top of each forum page, you'll see a link to "NEW POSTS" which lists each of the new posts since your last visit.
Finally, on the BPL.com home page, in the "recent" posts section, there are two links for "LAST 50" (most recent 50 posts in the forums) and "MY NEW" (new posts since your last visit).
Of course, you must be logged in with your bpl.com user account to use these features so it can appropriately track this information in your server-side user account without placing cookies on your pc, thus, the information remains portable to you.
Please monitor this feature and report any bugs or otherwise unusual behavior to email@example.com."
