Because of the high volume of spam in comments lately we now require registration in order to comment.
Registering is a simple process. You will need a valid email address in order to register, once you have filled out the registration form you will be sent an activation email to the email address you use to register.
Registered members will be able to track their comments, edit and update their comments, and will have access to other member only features.
You will find the Registiration link on the sidebar to the right below the Login box.
