Ok so some people have been having problems registering for SMS Updates.  I can’t reproduce the problem one hundred percent of the time.  To register for the updates (normal text messaging rates apply) you have to register for the site first.  When you go to your profile settings there is a tab that says Subscribe to SMS.

If you have problems subscribing respond to this thread and i’ll email you.  If you can’t comment on this thread then you shouldn’t be able to sign up for sms updates anyway.
