that didn't seem to work the way I expected.
I asked someone to use my nick in a sentence and I was hopeing that my system would send that message to the channel that I was AFKB but would return later.

I saw no reply to the channel

the /away "message" was transmitted to the channel when I invoked it but when someone used my nick the message was not automatically responded to by my system

Maybe this can't be done?
again, thanks for your time
