You can add your 2¢ worth in a couple of different ways here.
First, you can comment on any blogpost. Just click on the comments link at the bottom of the post, and then add your comment. You can post anonymously, or you can tell us who you are.
Second, you can become a contributor yourself: write your own blogposts for others to comment on. To do that, just email Dale and he’ll turn you into a contributing member of this blog. Then just log in and add your own ideas!
