In this server you can request any level made in Geometry Dash so 2kb (a Geometry Dash Moderator) can check it and depending on whether he considers the level to be of enough quality, it may be sent to the developer of the game: RobTop, so he could possibly rate the level in-game. There are many requests servers out there, but you should to request here and see if you're convinced by 2kb's standards. It is always tried that levels are sent before usual rate time, so they have a good possibility to get rated :)
