Raven script has been going for around 5 years now and has become very popular among irc users. Raven script is mostly built with dialogs.
Raven Script is perfect for new beginners to irc pros, also great for ircops too as raven script has almost every ircop command in dialog.
I see a lot of people asking for an ultimate script. Not many people can say theres is a ultimate script but Raven Script can be as it has almost everything from simple aliases to extensive dialogs. With your help and comments this could be a truly ULTIMATE script.
Apart from script you see and use there are also a few scripts that run in the background that you dont see. For example there is an auto updater that checks for new versions online, if there is a dialog will pop up asking you to update and if accepted this will auto download a update.zip to ur mirc dir, extract and add/replace with new files all auto. Then it will auto delete the update.zip for you.
