Welcome. I personally am glad you are enjoying mIRC
Please realize, by asking 'what's the best script' you will get as many responses with different results as you will get responses. The 'best' script is the one you take the time to research what you want your mIRC session to do, and you write it accordingly. Sure, you can d/l something off of some web page, but it will contain too much or not enough of what
you want and need. Additionally, there can, and in fact are a lot of spy/worm/virus scripts out there, that can be bad for you and or your computer.
Keep it simple, keep it clean(of worms/virus/spyware) and enjoy chatting!
