What is the recommended way to set up my IRC nickname?

Please follow these steps to set up your nick and configure your client. Check off each step to make sure it's been done:

Select a permanent, master nickname. If the nickname you want is registered but has expired, just ask a staffer and in most cases, we will be happy to drop it for you.

Please avoid using the name of a community project or trademarked entity, to avoid conflicts. Write down your password and be sure to keep the sheet of paper in a safe place.
