okay , me too i cannot build this Idea in my head
that's not i want .. i don't want to alert users to all new posts in forum , only new posts in user's threads when user he is a poster.
Focused with me , now i write this thread i will Receive a notification tell me (kh99 write a post in your thread .... read it)
and want too, you will Receive a notification tell you (omardealo quote your post on this thread .... read it)
Regardless of his last visit, I want to show the alarm until he delete it or to see it .
that's it .. !

I'm thinking to select all posts in user's threads , Except that by him and that read it ..
posts that by him , ok i know how i know it
but how i know user read this post or not ? can i use the table (postlog) or there is another way ...

Thank you !
