AFAIK $chan().mode just stores the value of raw 324 when you join a channel, so it would be dependent on whether the server provides +f (or any other mode+parameter) in that raw response. IIRC +f is something to do with flood control or something(?) in which case I think it's only made known to users once they're opped in the channel. If so I assume the network sends a new 324 upon the user being opped. Maybe mIRC doesn't update $chan().mode in that instance? I dunno, that's all supposition, maybe you can confirm if I'm along the right lines of what +f does and how it behaves.
