Greetings,

Adding new areas to /yell is closely connected to server stress, so it's not something that can easily be done without the proper consideration. The team feels that there are no issues with the current areas that /yell extends to; however, if there are other areas with high demand or areas where if you can't see chat it's problematic, then please leave your feedback and the development team will take it into consideration.

In regards to the suggestion for a /general chat channel, for the same reason mentioned above, it would be difficult to add this.
