Asks <nickname> what irc client they're running.  Their IRC client may or may not show them that you've asked for this information.  ChatZilla currently does not.  If you do not specify <nickname>, ChatZilla will ask the server for the version of the IRCserver software it is running.
Zeptá se uživatele <nickname>, jakou verzi IRC klienta používá. Tyto informace může IRC klient uživatele poskytnout, ale také nemusí. ChatZilla je v současné době neposkytuje.
