Livesimming

I'm interested in giving this livesimming thing a try, but I have questions about it. When's the best time of day and of the week to do it? What do I need to get set up? How much notice do I need to give? What do you think I should I do on my livestream? Have you done one? If so, where can I find it?

I'd love to hear about your own experiences with it. :)
