Good morning! Happy New Forums time, everyone. 
We’re still working out a lot of bugs; make sure to include them in the Website Bug Report Forum so we can smoosh em.
I’m following up on a few things already, but I can answer a couple questions:
-
Ignore: We do have a story in for this for feature development. It’s not part of the traditional Discourse offering, but we’re using a modified version that our Web & Mobile team has been partnering on with the Discourse folks.
-
Likes: This is limited based on Trust Level at first, but grows exponentially as you continue posting on the forums.
-
Avatars: We’re currently pulling all characters above Level 10. This should be pulling Armory data (exactly like the old forums), so avatars should update with those. Blizzard Avatars will be back Soon™️.
-
Notifications: You can choose what level of creepin’ you want to do on a specific thread. The levels are detailed below:
- Watching: You will be notified of every new reply in this topic, and a count of new replies will be shown.
- Tracking: A count of new replies will be shown for this topic. You will be notified if someone mentions your @name (disabled currently) or replies to you. Threads you read in their entirety will default to this state.
- Normal: You will be notified if someone mentions your @name or replies to you. Default for all threads.
- Muted: You will never be notified of anything about this topic, and it will not appear in latest.
Edit: Speaking of quirks, working on fixing my post styling.
