analysis board

From what ive heard you can use an analysis board with two (more??) people viewing it

I have a few questions:
1.How do I use this feature 
2.How many people can use it at once
3. Must both players be diamond members?

I believe that only diamond members can start the feature, but can invite anyone else, regardless of membership status, to their analysis board. I'm not sure how many people one can invite, but its probably above 5 people. It is accessed in the Live section on Chess.com, when you go to the time control menu the bottom has "analysis". Click that and go from there. Free members can't start one, only join one though.

Not sure if there is a limit on people, Streetfighter had over 5 when he did his lesson.

thanks 

Now that conjured a weird image. I initially only saw the name "Streetfighter" and thought of playing the Streetfighter video game using an analysis board.

Yes, keep the opponent on the back rank, continue with a Hadouken trap, and Shoryuken any attempts to escape.
