Subforum group activity

Hello again.

I will describe the problem in words. Without screenshots. There is a group (Class – https://l2rev.ru/groups/klassy/) In the group has a forum. This forum has sub-forums. I don’t want to create a lot of unnecessary groups. This is illogical. If I create a topic or write a response in the forums, does not create activity in the group ( Class ). It is possible as that to implement? Don’t want to create a lot of unnecessary groups and forums when all you can do in one. Please see the website. Group (Class).

If you create a topic or write the answer in the main forum, the activity is shown (https://l2rev.ru/groups/klassy/forum/). If you write in the forums – activity no. https://l2rev.ru/forums/forum/klassy/episkop-bishop/

Okay? If not I’ll try to explain more)

Thank You. You always help)
