One of the things that made me the happiest when coming back to CoH, (and I owe you folks big for that one, you are my heroes) was all of the positivity I saw in chat. People gushing over how much they love the game, how much they love the community, and all of the shared experiences and ideas. I will admit, I have had several very enjoyable and uplifting conversations on the help channel that were not exactly help-related. I'm sorry. But I think the clutter on the help channel is mainly due to a lack of a similar social outlet while in-game.
I know that, when I'm doing missions and leveling, I love idly watching people chat about a variety of topics, and join in myself. There are SG chats, and other outlets like just hanging around Pocket D, of course. But the fact that they are not a global sampling of the community leaves a lot to be desired. As far as I can tell, the best way to fill this need, help promote the general positivity it's been prone to, and clean up help chat for better service to new and returning players, would be to try and implement a global general chat channel.
I have no idea how easy this would be. It sounds like a simple solution, but, obviously with a game like this there could be any number of strange quirks that cause it to be more difficult than it appears. But that is my suggestion for something that I know would make the game ten times better for me, and I suspect many others. I will continue to greatly appreciate what you do regardless.
