Last time I tried it (well - the last three or four times) the form was not working for me. No category section, though the note saying it was compulsory was there. And (or maybe because I hadn't added a category) the "Save" button did nothing when it was clicked (whereas the "Preview" button did its usual unsatisfactory thing).

Problem even with an existing page. And I thought that I might be able to click one of the "Edit" links to do just a section, but no - as with blog posts, section editing seems to be barred despite the inviting link.

What's unsatisfactory about the preview is that you can't see what categories the page is in (or will be in) and therefore can't (without considerable difficulty) check that they exist.

Final gripe (for now) about the new Wikia-wide editing system is that it doesn't autocomplete edit summaries that you have used before and want to use again. Unless that's fixed, my edit summaries are likely to be even less expansive than they have been.
