None of those guys usually do it when I am around. Blackhawk sometimes steps out of line, but I ask him nicely and he just stops and apologises.

I will have a word with these guys about spamming the mic. If it's in their own language then I don't know what they are saying, so I can't discern whether its spam or not. I would feel bad saying "only English on the mics" because that's just unfair.

I will tell them when I am on (should be about 10 minutes, I am usually on when they are).
