As everyone knows, the main channel that everyone uses is General Chat. However, I think we need additional, more specialized chat channels. For example, one for advertising and joining Towns, another for asking for help, and another for trading, selling, and buying items. This would greatly help the server as people would be more able to see things in general chat, and get the things they need done quicker.
General chat, when there's a lot of people online, gets flooded every minute with people asking for help, which makes it very difficult to talk to other people unless they're nearby. If there's additional chat channels for different things, it'll lessen the amount of chatlogs coming into the general chat, and maybe even alleviate some lag on the server.
