I’ve improved the Planet Calibre agregated feed by overiding the issues I had with the fact that I used a static copy mad with planet of a wordpress blog located on my intranet.
The initial planet copy used to transport URLs linking to my intranet machine.
Now, I have reworked the templates so that it no longer links to it but uses local anchors, thus providing reliable permanlinks for the items.
We’re ready for syndication baby
