+ *
+ * Revision 1.41 2002/03/02 01:35:50 alex
+ * - Channel- und Nicknames werden nun ordentlich validiert.
+ *

+ * Revision 1.37 2002/02/17 19:02:49 alex
+ * - Client_CheckNick() und Client_CheckID() lieferten u.U. falsche Ergebnisse.
+ *
+ * Revision 1.36 2002/02/06 16:49:41 alex
+ * - neue Funktion Client_IsValidNick(), Nicknames werden besser validiert.
+ *
+ * Revision 1.35 2002/01/29 00:14:49 alex
+ * - neue Funktion Client_TopServer(), Client_NewXXX() angepasst.
+ *
