melee attack

ok, while ive been playing for the past 10 mins (first go!! sooo good!! :] ) ive been smashed across the screen and blown into oblivion :S just wondered if it was the melee attacks that sent people flying across the screen, and if so, once ive locked on what do i press to send them flyin? thanks in advance

yes its meele that sends you packing.second you lock on to them press primary fire which is i think left click then you start flying towards them you press right click as soon as your by them and you kick them,*try practicing*

thanks alot
