This may or may not work, but lets try. This thread is for people to talk to each other immediately. Realize it is very not private, so please please be polite. Being concise might work better too.
Maybe it can function like the long missing Live Discussion function we had years ago. Only messier.
If you see someone's online that you want to talk to. Post and mention @theirname and wait. Or you can PM them. Maybe this'll work, maybe it'll drift down stream.
