Vine has updated to version 2.0 and has included many new features and now lets you send private videos to friends. This new feature is called “Vine message” or VMs and lets you send a vine message to several people to start separate conversations, which means there is no group messages yet. The new update now lets you send private messages as well and send “Vine messages” via email or SMS to friends even if those friends are not on Vine. You can also customize your profile with colors from settings.
