When you create a new entry, you can have Movable Type automatically notify a number of services that keep track of recently-updated weblogs. When they receive notice, the services check your site to determine if it has changed since the last time you sent a ping. If it has, your site will be marked as updated.

weblogs.com, blo.gs and technorati.com have been provided for your convenience, but you can specify any number of other arbitrary services which support the weblogs.com XML-RPC ping interface (http://www.xmlrpc.com/weblogsCom) by adding the URLs for those servers to the "Others" box. Separate the URLs with carriage returns.
