Hi,
Yes you can allow people to see spectature chat. We use it on some of our servers. We have had people complain about "It helps you cheat" well a cheat is only a cheat if it gives one team an advantage. This dose not. Also it makes ingame banter a lot of fun. We like it a lot but then we are just freindly anyway.
We never type in enemy locations we just use it a chat and all can see it. just set the following command in you server config file.
seta g_spectate_allow_full_chat "0"
Obviously 0 or 1 is on or off.
