LuLu is a wonderful site that meets all publishing needs. For example, a person can create books, ebooks, photobooks (similar to iPhoto), or calendars all from this site. For educational purposes I really am impressed w/ their ebooks creator. All a user has to do is upload a file, choose from some different themes, and then create their ebook.
21 Classes is one of my favorite blogging solutions for schools. This free site allows teachers to create student accounts (no email necessary) to post (up to 10). Also, there is a paid ($8.95 a mo) classroom package which allows schools to create a blog portal. This allows up to a 100 students to blog while teachers have control over what gets posted or if comments are allowed.
