Only recently launched, WebmasterHub.net provide FREE SEO, including a
bulk ping service to submit sites, blogs and/or RSS feeds.  The bulk
ping service uses XML-RPC and the weblogUpdates.ping, or
weblogUpdates.extendedPing method if available.  The service currently
pings around 50 popular directories, but is still evolving.

See my blog post http://www.code-tips.com/2009/05/xml-rpc-blog-ping.html
for more details of the development the bulk ping service using Php
and MySQL.  The free service is written in Php, and utilises the
Weblog_Pinger class, which has been developed to ignore ping requests
if the server has already been pinged recently (5 minutes) to help
avoid being banned from submitting to a particular site or directory.
Additional functionality developed includes storing and retrieving XML-
RPC server and site/blog details from a database, allowing the system
to evolve as well as making it easy to update or add new servers blogs
and sites.

A list of the XML-RPC servers being pinged using the WebmasterHub.net
bulk pinger will be published on the website soon.  To suggest a new
server, please send details of the server (web address and port if non-
standard) using the feedback form on the site (see below for link).  I
will try to have any new server suggestions added within a day or
two.

The service is hosted for free at WebmasterHub.net to members.
Registration is quick, easy and FREE, an email address, login and
password is all that's required.  Please feel free to comment by
providing feedback on the site ( http://www.webmasterhub.net/contact.php
), or by emailing support at supp...@webmasterhub.net .

WebmasterHub.net also provide a resource directory for webmasters, web
developers and designers which cover many areas relating to web
development (including SharePoint and InfoPath).  Members can add new
resources and sites to the directory, which will be listed instantly.
Content is reviewed and removed if deemed inappropriate.  Users can
also submit a content breach report if desired.  The WebmasterHub.net
community forum for members is currently being set up, which will be
available soon.
