Aye the yellow goes away.
Well I joined a server and spawned. I was working out the controls when a dude on my team shot me. Gay.
Spawned again. Still trying to work out controls, some other team member turned up and used maximum strength to kill my ass. Gay.
So I left that server and looked in the options, found the controls, joined again, played for a bit and got pwned.
I suck.
