I read the following about pinging to weblogs.com, and want to ask, if anybody knows, if this is possible in Plone, and if yes, how (found on http://www.usrbingeek.com/): "Like most busy people that follow the blogging community I only have time to frequent blogs that I know have new content. I have my blogrolls set to mark all recently updated blogs with an asterisk. Sites that are not marked as new will hardly ever get revisited. Most habitual bloggers and blog readers do the same thing. If your site doesn't get marked as new then your blog doesn't get the traffic it deserves! To have your blog marked as new you must be pinging Weblogs.Com. Most blogging software has this feature built right in so just check the documentation or the Help file for instructions on how you can enable it. (Even w.Bloggar has the ability!)"
