Use Discussion Board Online for the comments part of your blog, ezine, online newspaper, or the like.
The benefit is that you'd be able to make use of the powerful user management features of Discussion Board, namely: registration, authentication, identification, anti-flooding, anti-spam, user profiles. There's also the moderator system, pre-screening, content splitting, pruning, sorting and filtering, discussion threads (who's replying to whom), topic ratings, word count, font types and colours, font-resizing, printable view, bookmarks, social-networking, and instant user-to-user messenging; and, of course, there's the system's statistics on posts, views, hours spent online, who's online, and more.
Run a blog or an online publication completely in HTML, without an application server or a database. This way, you can concentrate on things that matter most for your publication: design and content.
