Is there any way to configure "New Posts" option? I would like to exclude some threads so i wouldnt get any information about new posts there f.e. anime, predictions etc.
Thats not possible. What you could do however is subscribe to threads you like one by one. On the top of each thread there should be an option to subscribe to it. There is a drop down menu when you click on 'Thread tools'.
All your subscribed threads can be found at 'User CP' > 'List Subscriptions'.
If you want to file them into categories you can create folders too.
