Start a blog using one of several widely available free blogging Web sites, such as Wordpress, MySpace or Blogger. Generally, free blogging Web sites only require that users have an email address. Most programs are very user-friendly and are easy enough that even a beginner can create a blog without extensive computer knowledge.
Search for daily blog meme forums. A meme is simply a creative writing exercise, with several participants, that occurs on a weekly basis. If you're starting on a Wednesday, for example, you might want to try a Works-For-Me Wednesday theme, where blog users post their thoughts regarding tips and tricks that they've found to "work" in their lives.
Decide if you'd like to include photographs in your blog. "Wordless Wednesday" is a popular meme, whereby bloggers post a photo. Photography is a great skill to compliment creative writing, and a combination writing/photo assignment is a great way to practice creative writing skills.
Use your blog as an online journal. Many novelists and professional writers use blog memes as creative writing prompts and keep personal and professional journals on their blog.
Continue assigning memes every day. You can even let your creative writing student choose in which memes they'd like to participate. There are blogs devoted simply to publicizing each of the available memes, and participation is free.
