Just basic ephemeral chat. Like IRC. Really had no intentions of anon chatting, but I do see the interest and I think it's cool. I haven't touched the coolr code in months! It didn't really catch on, but when I saw that bitchat added something similar I figured I would try and add support for it just for the heck of it. As you mention though, one of the things missing in coolr is the ability to be anon so Ill try and it that in shortly.
