There's only a
Game-Request thread and a
Game-Release thread for that one. To post a DMTL patch I need a Translation-Request thread.
Also I need someone to play-test prototypes and asking for that in those 2 threads is pointless.
Edit: Once I have a finished/tested DMTL I could request ownership of that Game-Release thread, but I doubt that's worth the trouble. I think most people happy with a MTL played the game already so me replacing the MTL there with a DMTL, would just make some people upset including the original Uploader.
So just having a Translation-Request thread to post it seems like the better option, and it's not like there's any rule preventing you from asking for a better translation in a new thread.
Edit2: I guess I should mention that I already have a DMTL for it. It's really just about someone testing it and having a place to post it.
