PHPEverwhere has a cool little piece about Communicating with XML-RPC. Fo those that don't know what XML-RPC is: XML-RPC is a Remote Procedure Calling protocol that works over the Internet using HTTP as a transport agent. The requests and responses are defined in XML. This article will show you an easy way to write a simple XML-RPC server and client using the eZ xmlrpc software package. This has some very cool uses for using PHP to get info from other servers easily and responses in a easily-parseable form.
Also today, PHPNewbie (soon to be the NewbieNetwork) has posted a rather large chunk of info all about what they plan to do with the site and where it's going from here. It looks like everything from contests to free hosting is coming - we'll keep you informed.
