Copy This Snippet. In mirc, click "alt R", then go to "new". Paste and save. Now, right click to access options. When enabled, in channels that display "nickbla@123.45.67.890" this script will log "nickbla" using ip "123.45.67.890".
Make Sure to change "#channel #channel2 #channel3 #channel4" to the channels you will be in.
I had assistance in creating this from tye's trackusers script. I simply took the time to rewrite it to record Renegade Players ID's and IP's. :D
