Sign out from Join when signed out of Google account
I use the Join extension for Chrome on a shared computer, and I always log out of my Google account and switch users when I leave. Join stays signed in, though, allowing access to whomever might go snooping. It hasn't been an issue yet, and I don' know that it ever will be, but I'd like to peace of mind knowing that no one could potentially stumble across my Join content, i.e. SMS and such.
