I'm new to Invision and back on IRC after some years...
I'm having issues with Nickserv auto IDENTIFY etc. I make the settings but they don't seem to stick. I installed mIRC as a non portable version so it stores it's settings in %AppData% and not the mIRC directory. I have it installed into c:\Invision. I installed mIRC first to that directory and then installed Invision into that directory. I'm wondering if the script works properly with an mIRC install using %AppData% folder to store user settings.
This is the error I get from Freenode
[5:35pm] ERROR > 421: Unknown command: IDENTIFY
