I believe that would be financial futures. http://www.elitetrader.com/vb/forumdisplay.php?s=&forumid=41
Currency futures are considered different animals, not just on the broker level but on the exchange level, which is why they have a separate groupings on the CME site for both. That's why they have a currency section here. It's not just for spot fx trading, altho most seem to think that it's the only thing allowed in that section. Others have started threads on currency futures in this section so it's not forbidden. The subject matter for most currency futures trading would overlap what is already there in the currency trading section anyway. If you have something to put forth, I say post in there.
