how about isowner and iscreator too? What about isoper? Well I know why isoper would be a challange... but the other two would be nice...
you do relealize that your gonna need to get all three lists before isban, isinv, isexc will work of course. That means sending three mode commands.
/mode <chan> +b
/mode <chan> +e
/mode <chan> +I
These can be done at anytime (even outside the channel). Though mIRC can't keep track of changes unless in the channel.
$iel(#channel,N)
$iil(#channel,N)
Those 2 had been added upon my request.. but I'd like to have isexcempt and isinvite too, like isban
if (nick isexcempt #chan) { bla bla }
This could also be done by a script, but why not built-in?
