Zombie gwene groups?

[Resending this through e-mail because of the gmane authorizer issue]

Hello,

I am trying to subscribe to

    http://www.maisfutebol.iol.pt/rss
    https://inimigo.publico.pt/feed/

The web interface at http://gwene.org says both feeds have already been
subscribed, but I can't access the corresponding groups, the server
replies with

    411 No such group gwene.pt.maisfutebol 
    411 No such group gwene.pt.publico.inimigo 

Can this be solved somehow?

(In both cases, those are feeds which, unfortunately, don't carry the
full article. While this is definitely not optimal, having those
available through gwene is still useful for me; please let me know if
you don't want to carry such feeds.)
