you need to specify that the user needs owner access or OPER override +v to use

mode # -q $rname

some networks does not has "access" as alias in services, and the command "clear" will clear the entire list, not only a specific level

 access # clear owner $rgate 0

if someone uses

mode # -qaohv $str($nick,5)

they wont have any privileges to "deop" or "deowner" someone, to use "mode"

for what is this line made for?

mode $me +h $hget(data,# $+ q)

UMODE +h in some networks are only for Staff members or IRCops
