Once this update has been downloaded on your server, if you have the permission ichat.reload, typing a chat message containing "!reload iChat" will reload the plugin.
Useful for when you are configging the plugin.
NOTE: I am aware that the plugin bypasses most /mute systems, and it will be fixed in iChat 1.4 which will release soon. (the iChat plugin will have a mute system of it's own, which can't bypass it's self)
