A bug related to private/group chatting has been fixed. As it works now, if you click on any Chak De link, the window will be Public, Private or Group depending on context.
1. Original Blog Entry is private: In this case, all the replies are also private, by inheritance. Any "Chak De" link within this Blog Entry will be a private window, and all messages will be private posts and IM posts will go to the participants of the public Blog Entry.
2. Original Blog Entry is public, but one or 2 replies...

are private. If you can see the private post, it means you are a participant of that private group. If you click on that Chak De link, this would be a private window. If you click on any other public "Chak De" link this window would be public.
In all cases, the top of the Chak De window will clearly says if this is a public or private chat/blog, and who the participants are.
Thanks.
