Getting sick of people asking why they can't spectate properly in this mod, we been getting accused of keeping it a secret and it isn't as far as i know, so i thought i would explain how it is done, i only found out myself last week (thanks Pinky)
When in game click escape key, choose spectator mode, this will take you back into the map and above all the other players, leave spectate mode then choose "assign team" again but do not choose "class", then click the "back" button at the bottom of the page, it will take you back into spectate mode, then just click with your right or left mouse button to find the player you want to spec, hope this helps.
