Affiliate and Partner channels currently each have a page that displays the benefits for being subscribed to a channel (the one found at twitch.tv/subs/[channelname]). With the integrations that many services have with Twitch (like Discord), it may be a cool feature to give Affiliate and Partner streamers the ability to edit their respective page saying something like "Subscribers get access to a subscriber-only Discord/ Subscriber-only Discord channels." Or even custom benefits such as "Early access to some content" for example.
