The Wyrmrest Accord Realm Forums are the official Blizzard Entertainment Forum for the Wyrmrest Accord server.
This is a good place to advertise events and guilds.
Unfortunately, according to users on the forums themselves, the moderation staff on the official Blizzard forums has a history of banning users for making comments in support of LGBT people and things like Black Lives Matter. They also have a tendency to allow bad behavior to go unchecked. This makes the forums not a good place to socialize but there’s no harm in sharing information there.
