Code:
/* Spectator Chat - 2.0
* -
* This plugin allows spectators, ready roomers, and players in a team to
* talk to each other (through global chat). Team chat is still
* restricted to going only to the player's team, rather than globally.
*
* cvars:
* mp_spectatorchat (default: 1)
* Set this to 0 to disable the plugin on the fly.
*
* This plugin also auto disables itself when tournament mode is on.
*
* 1.0->2.0 changes: (1.0 was exclusive to modNS)
* o Made AMX Mod X 0.20 compatible (trivial)
* o Fixed bug where players entering an empty chat string would be sent.
* o Something else which I forgot, but I assure you, it was good!
