If the 'flaming' (which isn't always that big a deal) between players really gets to you, hit the F7 (maybe F9, not sure?) a couple of times and you don't need to read chat anymore.
you're right, it would be a great thing, but this doesn't let you chat with someone you want to greet, for example :/
i mean, i don't wanna disable the chat for the constant server flaming..i wanted to be free to read what people write without getting nervous almost all the times :|
anyway i flame too sometimes, i think is normal doing it sometimes in a rage moment or something, but i wish there wasn't need to flame every single time you kill someone, even when you do nothing "noobish"
