World of Warcraft Cataclysm players using the MerfinUI interface share setups and addon help.
MerfinUI gathers Classic Cataclysm players around a popular custom interface, so a lot of talk centers on UI setup and addon tweaks. Members share their configs, troubleshoot installs, and help each other get a clean raid-ready layout. There's general WoW chat too once the setup questions are sorted.
