If you are an existing customer of Lockr, and want to manage your sites, you can go to the Lockr Classic Dashboard and have the same experience you've always had. If you'd like to try out Lockr 2.0, your account and any keys set prior to this week are available in the 2.0 system.
Any changes to your site's plan in either dashboard will take immediate effect. However, KeyRings created as part of the Lockr 2.0 beta will not be accessible via existing Lockr integrations. Be sure to use the Beta version of the modules and plugins to access Lockr 2.0 KeyRings.
