Introducing Stride

I was wondering what this means for existing HipChat users. My highlights from the [FAQ](https://confluence.atlassian.com/stride-documentation/upgrad...):

> We'll send your admin an email when we're ready for you. > All of your rooms, teammates, files, custom emoticons and message history from HipChat Cloud will be in Stride. > In the future, all HipChat Cloud teams will be encouraged to move to Stride. > Starting soon, we will begin to upgrade all HipChat Cloud teams to Stride. > HipChat Cloud will remain in 'read-only' mode.
