Ok... so does anyone have experience with the topic in subject? I've tried to find the info via Google but could not find anything that would point me to the best solution.
On the pingomatic.com website they say that you can use this URL: http://rpc.pingomatic.com to ping the blog services on their list when your blog is updated, but no word on the format etc. They say it should be similar to the weblogs.com ping service so perhaps if someone has experience with this one it could help too.
As always, any idea is welcome!
Tomas
