I added some more functionality to the plugin. I am not sure if I should keep posting these here, but I don't want to steal waertf's credit.
This has the same mods as my previous post (SnareSpeak Fix, and no need to type !hear unless you want it off), but now spectators can see the team chat from both teams as well!
I have been using this modification on my server for weeks now, seems to be working great!
