GT.ru has bookmarks?
The BOOKMARKS at GT.ru are here in the Forum area.
On any post thread (like this one), you will see the "Add Bookmark" button towards the top-right near the "Reply" button.
The recent enhancement was making this button MORE available then before. You can now "bookmark" threads that are locked or in areas that don't allow you to reply. This allows you to bookmark any number of important (to you) threads to find them more easily again in the future. You can see all your bookmarks using the "My Bookmarks" button in the top-left section of buttons: "Home" "Help" "Arcade" "Search" "Profile" etc.
