Matts writes "Michael Nachbaur, a long time AxKit contributor, has released the first version of his AxKit based CMS, Callisto. I haven't tried it yet, but it sounds cool, with features like WYSIWYG XML content editing, transactional site deployment to multiple servers in a farm, vhosting support, and so on. Michael says we're to "Attack it, beat on it, and otherwise try it out.". So what are you waiting for?
