This is now unsupported, as this is now patched in live TF2.
Stops players from spawning during the round in arena mode.
What this plugin does is perform an action if the player changes classes and spawns in during the round on an arena map (adjustable via arenamaps.cfg). You can keep the standard slay settings or have some fun by putting your own humiliations.
(Also this is my first public non-FF2 related plugin but still related so yeah.)
