# automatically rejoin to channel after kicked

# /SET autorejoin_channels #channel1 #channel2 ...
# /SET autorejoin_delay 5

# NOTE: I personally don't like this feature, in most channels I'm in it
# will just result as ban. You've probably misunderstood the idea of /KICK
# if you kick/get kicked all the time "just for fun" ...
