Can you explain what TRS refers to, please?

I'm not sure if it's relevant, but the message wall posts and article comments take a bit longer to migrate FYI. The banner notification on that wiki states that both of them are still under migration. So if it's something from any of the two that you were referring to, then you can rest assured that it should be back soon. 🙂
