It would be good if mIRC came with a swear filter.
Alot of people either dont like to see swearing on their screen (from other people), or have kids that lurk around the computer.

I was going to write my own swear filter.

on ^*:TEXT:*:#: { echo $chan < $timestamp > < $nick > $replace($1-, swearword1, ****, swearword2, ****, swearword3, ****) | haltdef }

But thats not that clean.
