Re: Needz - a new classified service with federation

Sounds nice..

Do you have any developer documentation on how you are extending
PubSubHubbub and Salmon, i.e. how do you model offers?
Are you using GoodRelations by any chance?

In the iPhone app, is there a configuration screen that allows me to
"choose" my Needz server?

Is there an open source implementation for setting up my own Needz server?

all the best,
Markus
