'maxNickLength' is a maximum length of the nick. Various servers restrict the length of the nick. '30' should be enough.

Yes. When you start application, you could pass next options: Yes. When you start application, you could pass next options:
-g, --genconf Create configuration file template. Attention! It will overrite your existing configuration file. -d, --daemon Start application as daemon (experimental)
-n, --nomessage Don't print any messages anywhere -g, --genconf Create configuration file template. Attention! It will overrite your existing configuration file.
-v, --version Application version -s, --silent Silent mode. All program messages stores to the 'output.txt' file
--help Help message -v, --version Application version
Pay attention, that '-n' is just for turning-off messages, there is no stuff like daemon-mode inside. Yet. --help Show this message and terminate application
Any chance to log more than one channel? Any chance to log more than one channel?
