How to update the list of games in the "Playing" dropdown

I've been running a Ubiquity System game in the "Hollow Earth Expeditions" setting for more than a year now and I'm finally getting around to updating the listing for the game.  I noticed that the "Playing" dropdown does not include "Ubiquity" or "Hollow Earth Expeditions" but I don't see a way to add these.  How can I add new entries to the Playing dropdown?

The games dropdown menus exist to help standardize the options available (example: 4E vs. 4th Edition vs. D&D4). No matter how many games are listed, some may not make the cut. Games are added to the list periodically by the Devs. This ensures obscure listings gain greater visibility when sorted via the Other Games option and helps keep away “empty” search listings for underrepresented titles.  If you feel a game should be listed, encourage your community members to play and post often. The more community attention a title receives the more likely it is to be added to the list.  You don't need a system to be in the dropdown list to play it; use 'Other Games' and put the name of the system in the listing text, all the forms of it someone might use.  Actually play the game.  Ask those you know who play the game to do likewise. You don't need a system to be in the dropdown list to have a character sheet for it; ask in the Sheet Request Thread, Consolidated, mk I thread for someone to help you make or make a character sheet that can then be added to the list of character sheets available to users for their games. You don't need a system to be in the dropdown list to ask the writers of a system to think about licensing their system for use with the Roll20 VTT; talk to whoever produces the system you're interested in, tell them how interested you would be in being able to have an Official Character Sheet and Official Compendium available on Roll20.  Ask those you know who play the game to do likewise.

So I added "Ubiquity" as instructed above (used "Other Games" put the name of the system in the listing text) and then attempted to find my game by selecting "Other Games" and then putting in "Ubiquity" in "Matching Keywords".  Nothing came up. What should I tell the folks on the Ubiquity Facebook group (165 members) if they want to find Ubiquity games on Roll20?  I'd also like to tell the folks on the Space:1889 Facebook Group (1,028 members) how to do so as well. 

It can take several hours for a game to show up as the search engine syncs up the current index with the database every few hours.

Also, as Gen Kitty said, it's a good idea to put multiple versions: so put Ubiquity, and  Hollow Earth and HEX , and any other common terms people would use for the game.
