thanks LeChuck, I have been to that website and another XMLRPC website and have been reading them for the past few weeks.
what I need to understand is, what kind of information would I get?
a ping is just a packet of small data... what kind of data would my server receive from a ping?
can someone show me a sample? can a ping include an RSS feed?
if so, then I can take the ping and parse the RSS feed.. if it is different than the previous RSS feed for that site then I can make an update to my site
is that all I have to do?
