I have a suggestion
Please avoid extended discussions in comments. Would you like to automatically move this discussion to chat?
In this part why can't we mention that the commented user is online or not?
Reasons for this feature:
Without knowing whether the commented user is online entering chat room will lead to waste of time especially when users with slow internet connections will have to wait for his/her reply and if we state that the user is offline then the user won't migrate to chatroom
