Movable Type has the capability to automatically notify other blog sites when you post. This capability is called “pinging”. To enable it in Movable Type, do the following:
1. Login to your blog
2. Click on “Weblog Config”
3. Click on “Preferences”
4. Scroll down to the “Publicity / Remote Interfaces / TrackBack” section
In the “separate URLs with a carriage return” copy and paste:
Pinging that one URL (ping-o-matic) will then automatically ping about 10 sites, the magic is detailed here. Read their “And… So why would you want to be on these sites” for a quick intro on why pinging is the thing to do.
Hope this helps you get the word out about about your blog
