I attached here a update within a new cvar:
Code:
// Indicates several adjusting options for the plugin general behavior.
// The flags are additive. A value of 0 will not enable any of the options.
//
// 1 - Indicates whether the use commands should output on the chat or
// not. For example: If this is enabled, it will not show `RTV` on
// chat when a players does the `say RTV` command.
//
// For example, if you want to mude the options 1 and 2, use 1 + 2:
// gal_general_options 3
//
// Instead of:
// gal_general_options 0
//
// Default: 0
gal_general_options 0
If you set is to 1, the RTV will stop spamming on the chat.
Your current `galileo.cfg` file does not contains this setting, you need to add it there.
