I’m not sure if this is big news to all of you, but for designers/developers who work on sites run with Movable Type, it’ll probably be useful. Up till now, if you used custom submit images at the bottom of a comment form the entire comment-posting process wouldn’t work the way you expected. Either a comment would get previewed, but not posted, or it would put the user at the wrong template afterwards and wouldn’t record the comment. This behavior bothered me back when I was designing this iteration of the Business Logs site, since I had custom submit images all made up, but I could never figure out the problem.
