To help reduce server load and improve overall stability, we have temporarily disabled the auto-join functionality for General chat in all regions. Until further notice, if you wish to join General chat, you can type "/join General" into the chat window or click on the cogwheel in the upper left corner to access the Join Public Chat menu. We will provide another update whenever auto-join for General chat is turned back on for each region.
Please note that we will also be making a change with patch 1.0.3 so that if you leave General chat once, the game will remember this preference and you will not automatically join General chat again when logging in. While we don't yet have a date to share for this patch, we anticipate that it will be released before the end of the month.
