One of the best places to start whenever you're looking for something is
Google. You might try
this trivia bot or view Google's
results for a search on "IRC Trivia Bots". Sites like
www.mircscripts.org have an integrated search feature.
Note: Many scripting sites do not check their submissions for viruses before allowing the public to download them. You should always be very cautious when downloading anything from the Internet, scripts included. I suggest you get 2+ virus scanners (suggestions can be found in
this thread) and scan any files you download with both of them. The reason for using 2 (or more) is that different virus scanners detect different things and for extra precautioun it's good to do a couple of checks. When scanning one file or a small folder it takes about 60 seconds of your time, so not a big chunk out of your life to ensure your security!
Have fun!
