I spent some time tinkering with Silt today. First off, I took a look at the CPu usage thing, and found spam attacks - I posted on that earlier. Then, in response to a couple of requests, I added a feature to the online edit page. First, finding existing posts by ID was broken (that's now fixed). Second, I added the ability to delete a post via the web form. Yes, I still need to add an interface that allows for the same treatment of comments. That's coming.
