The problem is still unresolved and the same as shown in my quote above. I'm opped and so is my bot. I can't for the life of me figure out why it doesn't respond to me upon the trigger @slang or !slang...
The network I've tried your script on is a nonstandard IRC network called Buzzen. If you know of it, you can go there and debug your script and see if this is a network related matter.
