We've all been asking for direct messaging for a very long time now and we have questions:
Will it be AJAX-coded? Meaning, will the page refresh whenever you send a message and when you receive a message in the same page session? Will you have to refresh the page so you can see the person's new message or is it instantly live like live chat?
Will it give a typing indicator when the recipient is replying?
Will it show if you or the user is online? Can you toggle it on or off?
