The most obvious bit, of course, is to register your nick, which is done simply with /msg nickserv register $password (from the nick you want to register, of course). Next, /nick $altnick to another nickname and register this nick as well, again with /msg nickserv register $password. Then, link the two names by doing /msg nickserv link $originalnick $originalnickpassword from the secondary nick. This will document that both nicks are owned by the same person, and will allow services to leave you identified if you switch from your primary nick to your alternate and vice-versa. We encourage you to set your nick up in this fashion because, if configured correctly, it allows you to connect from your secondary nick in the event that you try to connect to freenode when your primary nick is in use. If you generally auto-identify, you will still be able to identify, receive your cloak and other relevant settings. Traditionally, the secondary nick is master_ (note the trailing underscore), but feel free to use whatever you like.
