Kuddi: xmlrpc'ing vectors

Hi!

According to some postings in

	http://www.mail-archive.com/[email protected]/maillist.html

exactly the same question must have been posted in this list in sep 2002.

Sorry for this, but unfortunatly the kxmlrpc mailing-list archive is not
available.

Any idea, when the archive is going to work again?

Greetings,
Henrik
