Is it possible to limit TL0 to posting in one category?

@manu-p

but things have changed since then.

I don’t think anything has changed. It’s still about posts you read, topics you visit, and time you spend reading. No posting is needed for TL1.

You must meet all the requirements. See also:

Do I have to comply with all requirements per level?
Yes. The listed requirements are “and”; you have to fulfill all of them.
