Last week, I was kicked out from the Bobby Fischer's group without telling me what the reason was.  I joined again.  Now I am kicked out again under the same circumstance.

I was told by somebody that he also suffered the same fate in the group after having a disccussion that may be disliked by one of the admins there.

What is the policy of the chess.com about this?  Was my ejection justifiable?

It's a private group run by the group admins; chess.com has no say in what goes on.

okay, thanks oinquarki.  Now I know.

Why not start your own Bobby Fischer group?

Thanks ipawndown.  I'd like to but I don't know how to do it.

You need a turnip to start a group.
