I don't think there is...?
SRB2Wiki said:"The Official SRB2 Master Server is divided into two separate "rooms" which serve different purposes. In the Standard Room, netgames using the official gametypes implemented into SRB2 are hosted. Servers that play the game in a different way than intended through the game, such as Roleplaying or Hangout, are hosted in the Casual Room. During the OLDC judging period, an additional OLDC room is open for contest judging netgames. "
Sorry, I meant OLDC Room, not server.
