International Comment Leaving Week is November 21-28. Don't all bloggers enjoy a little comment love? :)
It's easy to participate by signing up HERE. Then, each day during the week, leave 5 comments on other blogs, and follow/comment on one comment that's been left on your blog. (That means that you'd be leaving six comments per day all week long.) It's easy, fun, and a great way to discover some new-to-you blogs that are out there.
