I have been researching this topic for a few days, and your site gives me the hope i was starting to lose! I am a student that is working on a project that will run an XML-RPC server doing something similar to what weblogs.com is currently doing (and now your site is running). One of the problems that I have already run into is trying to figure out how Wordpress is sending their pings. Since they are using XML-RPC for their pings, I would have figured their data would be coming through a POST or GET string in the HTTP. For testing purposes, I setup a small script that grabs any information that is passed over from a ping and emails me the POST and GET strings. Movable type works perfectly, but Wordpress shows me blank strings. If data is being passed over HTTP, doesn’t it have to be in one of these 2 strings?

Another thing that I have been wondering is if there is a standard for setting up the server. I know that the weblogs will add to their list a link I give them, but what about the method location on my server? I am expecting that I have to put my server in the /RPC2 folder since that is what Weblog.com did (and that seems to be the standard now). I found the following line on the XMLRPC site — ‘To tell Weblogs.Com that a weblog has changed, call weblogUpdates.ping on rpc.weblogs.com, port 80, path /RPC2.’ Is there going to be a specific name that I have to use for the server also?

I know these are a lot of questions, but if you can help out in any way, I would greatly appreciate it!

Thanks in advance,
