Hi,
on my blog I allowed also non autenticated user to post comments but, if someone put his home page url, the system give a wrong url, which start with my Url plus the url of the author.

I.e. If the author of the comment put in the form his url:
http://www.comment-author-url.ext
on the page the link give this url:
http://lacasadikikko.enricorotelli.it/http://www.comment-author-url.ext

You can see by yourself here, is the last one submitted: http://lacasadikikko.enricorotelli.it/racconti/separazione_consensuale#c...

Any help is appreciate
Thanks
