adding a new game to the menu?

I was just wondering if any one plays the firefly table top using a different selection on the menu or if it could be added? Im new to the table top games and im interested in playing that one or if any one plays it to under a different game title and willing to let me join.

The LFG games listing only includes games popular enough to always have something listed; the devs don't want empty result sets when people look for a game. Games without their own listing use the "Other Games" listing. There are people who play the Firefly RPG (someone has even created a character sheet for it), there simply aren't enough to warrant its own category.
