Description:
This plugin does for chat what sv_alltalk does for voice. Dead and alive and spectating players can all see each others chat messages. Team chat is still only visible among your team, but with no regard for whether you are dead or alive. By default this plugin works depending on whether or not sv_alltalk is on. It can be forced to be on all the time, as well as setting custom colors for messages that come from admins.
