hi,

go to the configurationmenu in the PEERanha client!
Click on the row with "IRC_Ident" in it! Change this value to something like your name e.g. Joe Smith. Don't forget to press return! Then click on "IRC_NickName" , enter your NickName and press return! Now switch over to the IRC-Window and press the connectbutton! The connect may take a while!
... You are logged in!
