What excactly is so revolutionary about XMIT? so far the only thing i've read is that it doesn't require delivery confirmation (or something like that).

However, when you type /fsend on (you have to be the one who sends), this confirmation isn't needed anymore, and mIRC will just keep sending packets, regardless of any confirmation being recieved (you can even see this in the progress bar).

Or am i mistaking?

you guys are so not L334
