I'm a big fan of MarsEdit for drafting and posting articles to my install of MT 3.32. However, I noticed that when I posted an article in MarsEdit, the usual pings that are sent when posting direct through MT weren't going out. Upon closer inspection I found that there's an option to enable this type of ping in MarsEdit.

So now when I post a new article, a ping is sent to Technorati, blo.gs, weblogs.com, and newsgator. The only problem now is that the ping that goes to the MovableType site isn't in the list.

So my question is this - what is the URL for the ping?

I'm a paid user, so if I publish directly through MT, the ping is sent and works properly.

Thanks in advance!
