Sorry if I expressed myself poorly
. I meant, that whilst the user is online, but idle (maybe away from the computer or having already closed the window) new posts should be stored stored. In the next 6 minutes 2 thinks can happen:
The member comes up again before being set to offline. All stored posts-URLs for him are deleted. He will see them (he has officially not been offline inbetween).
The member is set offline due to inactivity after 6 minutes: A post-URL digest for this time is sent to his address and further posts are notified as usual.
This Post-storing system, I reckon, needs some work. It would need another User-session column or to be saved in files individually for each member. (I don't know how myBB exactly works, never take a serious look at the code, but this it how I imagine it does).
It's just a suggestion I find very confortable. Maybe a little exhausting to implement, but relatively easy to add maybe in future versions of myBB
Edit: If I gather some time I could take a look at the code and try to doing it myself
. But that would sure end up with many security issues
Edit 2: Sending the digest may be problematic, because php, afaik, cannot control events by itself and trigger some commands. In frequented boards this shouldn't be a problem, because there's always someone calling a php, but on other sites that might be
