Note that this is a single development list for all OpenStack projects. You can use Mailman Topics (on the [Subscribe] page) to help with sorting and filtering messages. Please read the [recent] [threads] to see why suggestions to split the list by projects might be met with strong resistance. You can use Topics to filter the list and have nearly the same effect if you only want to see messages for specific projects.
