Hi again! After some months i corrected some mistakes in this code and added a few things to make it act like a typical IRC Client.
It will now use an alternate nick when the nick is already in use.
It will now attempt to join the channel correctly and not attempt before successfull registration.
It will now send a small adv message when it successfully joins the channel!
Change INPUT_CHAN_HERE with the channel you want!
Change INPUT_SERVER_HERE with the server you want!
Enjoy!
