tell me the detail definition of "members who read messages"

Occasional Visitor

Hi guys.

When I analyse a community,  I can't understand the meaning of "members who read messages".

Especially, what does "read" mean?

 When someone see the message while scrolling a community?

 When someone click the message?

 Or, is this case included "read" , when someone just see the message on e-mails?

 

I wanna know to activate communities. Thank you.

My understanding is that if the message is short and can be seen on the screen in it's entirety it is a read. If the message is long then you need to scroll to the bottom of the message for this to count as a read.
