You can start your own channel... Just type /j #YourChanName - You will automatically be an operator in that channel. Now you have to set yourself as founder. Ask an IRCop to help you. They are normally found in the main channel on the server, just ask around. I'm sure someone will be able to help you in regards to this.
Type the following in your status window:
/msg chanserv help commands
And read the info there :-)
