One of the features of a great roleplaying website (And plenty of awful ones) is an open instant-message chat. It's an easy place for users to mingle, find partners outside of a bulletin-board situation, and start networking and developing venemous cliques.
While building a custom chat is a serious ordeal, I'd be very interested in any attempts to host a Litphoria chat on an existing platform - Discord would probably be the best option; more accessible than IRC, more stable than a Java addon, and with the added mad-science of server bots. With the site being the size it is, it shouldn't need an obscene amount moderation to be functional.
And if a chat like this already exists, Discord or not, I'd love to know! I mean, apart from the two-way message chat. I know about that.
