Non-standard lobbies often require changing the Lobby name, Welcome message, and a multitude of modoptions, often requiring the Host to copy many lines in one by one. This is, or was, a tedious process. The lobby now supports multi-line input commands, allowing for the chaining of multiple commands in the same text message. (Depending on the size of the message this may be very slow and laggy process)
Separate your commands with a new line in a text editor of your choice before pasting them into the chobby chat. This supports both ! and $ commands, Here is a simple example:
$rename Experimental lobby
!bSet experimentallegionfaction 1
!bSet releasecandidates 1
