To expand on that, the username that is causing you the problems is your identd user name, which *may* be your e-mail (before the @) if you have it set up that way. Look in Alt-O > IRC > IDENTD. You'll see the user name field. That's your problem. If you have the use e-mail box checked, uncheck it. Then enter anything in the user name field that looks legitimate (ie. not qkjwt). Some networks will complain if you use certain symbols, no vowels, or various other things. Changing it will solve your problem.
You can change it either in the options or using the command that was given to you already. This was just to explain what was going on.
