Explain how to send a message to a specific node in the documentation

[Hywan]

Hello :-),

This is the second or third time someone asks “How to send a message to a specific node”, on the support ML, IRC or even comments. I think we should update the documentation ;-).

Hello Hywan,

As u say send a message to a specific node use " broadcastIf " method.

but my question is what should i have to pass in to the first argument in that method.
broadcastIf ( \Closure $predicate, $message ){...}
I didn't get any idea about it.
sorry i'm new to this library.

thanks,

@mspmakk Hi! What do you want to do exactly?

[mspmakk]

I am working on some notification updates module.
When I post some thing then other related user (friends) should get notified.

In short send some data to particular user.
so i though that it should be possible through " broadcastIf " method.
