mirc is great but how about adding a backgroud feature i think this will make it perfect
You can add backgrounds to windows by right-clicking their button in the switchbar and clicking "Select..." under "Background".
You can also specify backgrounds for the switchbar, toolbar and the MDI area (whatever it's called) by right-clicking on them.
You could also use the /background command. /help /background
try at least looking at the help file next time. please.
