#13 problems with servers

[Anonymous]

When you select another server, for example
irc.wanadoo.es
irc.irc-hispano.org
irc.arrakis.es
oslo.no.eu.undernet.org
yoy get this response:

>>> Welcome to Chatlet
>>> *** Looking up your hostname
>>> *** Checking Ident
>>> *** Found your hostname
>>> Your username is invalid.
>>> Connect with your real username, in lowercase.
>>> If your mail address were foo@bar.com, your
username would be foo.
!!! ERROR :Closing Link: carlossf by
Oslo.no.eu.undernet.org (USER: Bad username)

It seems to be an autentification problem, but i
don´nt know why if this servers don´t need
autentification...
Excuse my bad English, i´m Spanish.
