I never noticed this before (the yellow text in a notice on the top of the forums pages):
I like it! In fact, I think I like it better than the regular way of posting notices... you just can't miss this notice, even if you navigate in to the forums without seeing the "Regular" forums home.
Is it temporary or is it a new thing?
Because we now disable to front page view of the forums during maintenance and heavy loads we also lose the downtime notices on that page which seems to cause some confusion. To help mitigate this, we'll be using the forum notices to serve as a constant reminder (and provide updates) when we have server maintenance.
This is nothing new to beta players, they're used to seeing big red warning messages when they log in.
