Twitch update alerts
Provide a means of alerting users of notable and significant changes to Twitch as these changes go live. Something similar is in place for creators and moderators in the form of the "What's New & Feedback" icon, but this does not always cover every change. People should be alerted to all changes, even cosmetic ones, especially if key features would be affected.
In particular, it would be good if there could be an option to sign up for a mailing list for announcements made via the Twitch blog as well as updates to the Community Guidelines. This would be especially useful for creators/moderators but also for those who just want to always be up-to-date with these things rather than relying on other users or external sources to tell them later on.
