We just finished installing three new mods to the FF system:

Show Topic in View online page -- This mod shows what topic someone is viewing in the "who's online" list.
Welcome PM -- allows the admin to set and configure a "welcome PM" sent to newly registered users on his/her board.
Links in New Window -- Forces links in topics to open in a new window (like v2) rather than the current window.

All these can be enabled via the "Mod Center" in your admin panel.

Enjoy
