Forums General Discussion notification box in version 6.17

there is a notification box in the lower right of the screen on version 6.17 and it is annoying as it can be. How do I disable it or make those things go to the main channel? it blocks the scroll button and it just plain annoying. Please help.

Thanks,
Mir
