Successfully connected to chat room (newbie) on Friday and Monday --- when I attempted to login Tuesday and today get the following msg

* Connecting to (6667)
xx Nickname is already in use.
XX Nickname is already in use

* Disconnect

mIRC auto retries tries a couple of times with same result.

Searched previous posts saw one from/to NiGHtOwl on 03/06/2003 that seemed similar -- it suggested adding instruction lines under the alias tab. Don't know if this applies to my situation and if yes how to properly apply? There is already a bunch of instruction lines under the alias tab.

Any help greatly appreciated.
