CBTTC now uses Google+ Authentication to authenticate users to our system to encourage a "single-sign-on" environment across our systems. If you are a new user please click the "Sign in" button above. Existing users will have to be re-moderated so that we can associate your Google identity with your existing account. Upon initial sign-in an email will be sent to CBTTC system administrators to authorize your account. On authorization you will be able to use CBTTC’s Data and Inventory system. Please email operations@cbttc.org with any questions or concerns
