The menu "Quick Links" contains now the box "English forum - Forum Main Page - Russian forum". You need to register to see this menu in your navigation bar.
A new option has been added, allowing you to search new posts in a certain section. Open the forum you need and select "New Posts In This Forum" in drop-down menu "Search This Forum".
