Integration of Openfire with wordpress via pubsub

Hi all,

i’ve recently found a plaugin that can post my blog updates on Jabber via “pubsub”.

Excuse me for my ignorance, but i don’t know what exactly is a “pubsub” in openfire, and i don’t know how to create it to allow plugin connecting to my jabber server.

I’m using openfire 3.6.0.

Could you please post me some documents/how to for helping me learning something about that?

thank you a lot
