Mentality is a fair and honest young man, the things he's pointed out to you in this thread are absolutely true, which is why I agreed with him.

As for helping you find what you're looking for, I've had a quick search and so far only found:

Try it at your own risk, but that's the kind of thing I was talking about.

Again I would like to agree strongly with the things Mentality said, you should seriously consider upgrading. Earlier versions of mIRC such as the one you are using contain security issues (in some cases) which have been fixed over the years. The 6 series is the most feature packed and stable version I have ever used.

If you'd prefer to use a script, as many people do, there are several full scripts which are worthy of your time:

http://www.mircscripts.org/comments.php?cid=1991 (nonamescript)
http://www.mircscripts.org/comments.php?cid=1301 (peace and protection)

They can all be used with mIRC 6.16 and are feature packed.

Hope all of this helps.
