the mode +L is
/mode #channel +L #channel2
you need to specify a second channel to redirect the ppl
the +I, on channel means
that, if the channel its for invited +i, the person with the names on $iil (internal invite list), can join on channel without invites
the +f on usermodes its "Snomask"
the +s hides the channel from the /whois and /list
if i didnt make a mistake, you forgot the modes
