BuddyPress.org

And did YOU look at the codex?
Ofcourse, it was the first thing I did when I discovered the problem. I’ve been heavy googling for one hour after I made this question. At the codex there is info that the olny accepted parameters are:
{user_id, box, per_page, max}. Perhaps “box=notices” would be some point of interest (can’t check now as I’m away from working env) but obviusly there’s nothing like type

And about: bp_message_thread_has_unread()
I don’t want to check if the message I get is unread or not, but I need to make this filter on the level of query ( not display ), so I am getting only unread messages, not ‘n’ number of messages from which I am displaying only those that are unread because either way I will not display all of them or I will have to query very big amount.

I see the great power of BuddyPress, but I’m pretty new in this system (it’s my second day ) and I’m jumping through files and functions looking for some clue. I could optionaly make it dirty hardcode, but then everyone in my team would push me to the pit of inferno

//EDIT
Anyway: Thanks for interest
