BuddyPress.org

Hi all, I am non coder but fond of learning buddypress. I want to create a custom post type which will be attached with user navigation menu. From there user can post an article in particular category. Now I want to way notification process where the user with post in same category should get notification when other user publish post in that category. Similarly, if user creates and publishes the new post in particular category, he should get notification that that category has how many posts already available and who has authored those posts.
As I already mentioned above, I am a non-coder. So elaborate guideline are always welcome.
Waiting for help eagerly.
Thank you
