Also would it not be possible to turn off posts in a cat if it has children, so could be used soley as a sub menu?
This can be achieved by restricting the permissions for all users in that category to just "Find/Access" and "Read"
I'm not sure if it is a bug or improvement. The Topic/Posts queries and views are highly optimized to show massive amount of data, however the categories views are lacking in this area. We have a movies discussion forum where we create a category for every celebrity and artist whom users want to discuss. After a certain number these pages become incredibly slow to load.
As seen here https://discussimdb.com/category/4/celebrities
Do you guys have any tips on how this can be improved?
