I tried your script, and I replaced P with the P nick that I don't want, in this line:
Code:
if (%tabcompword == P) { sendkeys {tab} | .disable #tabcomp.p.catcher }


I just tried hitting P and then tab. I think the name I don't want was the only P nick in the room at the time. The script seemed to lock up. The nick I don't want completed itself on tab and then just sat there "fluttering" on and off very quickly. I had to part the channel to get out. I'm not sure how to fix this. Thanks.
