I just switched from MovableType to WordPress and am liking it a lot. It seems to do everything I want before I know I want it, but I can't seem to find one thing I used on MT. I was working with a couple other MT users where we would have our MT installs ping specific categories when we updated that category on our own sites. So if I updated Category A, the other weblogs would get a trackback ping to their category A as well.
I'm not see where I set up the sending and receiving of pings in WP.
I am running mingus if that helps.
