How to automatically deal with wrong way drivers is specified by the server option
/autokick, which can be set to
yes,
no (kick),
ban or
spectate. The option is set in the configuration file for a dedicated server or thru chat/command
/autokick in server console or in-game as admin.
ie.
/autokick=yes in config,
/autokick yes in chat/console.

The splash screen text is to be grabbed from a .txt file, controlled by the server setting
/welcome.
/welcome=file.txt
