vB 3.8.1: tcat value

[Terminot]

Hey

When you create a forum and select "Act as forum" as "No" then it uses the tcat class. However, I do not want it to show the tcat class, I want something else specified byself. So, to say it different, I would like it to show my own written CSS value (added in the main CSS).



So where it says "AutoQ" the class needs to remain "tcat".
Where it says "Algemeen", "Media" and "Diversen" the class needs to be "onderverdeling".

Which template do I have to edit to make it that way?

Thanks in advance.
