Slot, I made a Rocket Arena selector map (zip) and I don't know if you would have interest in running such a thing on your server, but I know it is incredibly difficult to remember the map names on the server.
I think all it would take is adding an exception in QuakeC to cause this single map's changelevel teleporters to function.
I actually made the map support single player, deathmatch and it should be possible to play Rocket Arena on it as well.
The map does have teleporters for some Quake Expo maps Sputnikutah/Rook ran on his Rocket Arena server and for some new Rocket Arena maps written by Aquashark.
Hydro, me and Yellow really liked those Quake Expo Rocket Arena maps that ran on Sput's server.
A zip I made of the additional maps indicated in the Rocket Arena Selector Map (zip link)
