Need Chatzilla IRC Help!

I logged off the chatzilla IRC an hour ago and now when i try to rejoin again it comes up with this message:

[INFO] Channel view for “#Sythe” opened.
=-= User mode for venom1 is now +ix
[INFO] No such nick/channel
[INFO] This channel requires that you have registered and identified yourself with the network's nickname registration services (e.g. NickServ). Please see the documentation of this network's nickname registration services that should be found in the MOTD (/motd to display it).

after that message's comes up, nothing happens. I don't no much about the IRC, so if someone could help out that would be great.

 

You need to re-identify. Type "/ns identify password"
